Abstract: This paper details the progress, achievement and status of the various CEA contributions to the Broader Approach projects: IFERC/CSC, IFMIF-EVEDA and STP/JT-60SA recorded since the 2012 IAEA conference.

I) Introduction The Broader Approach, BA, Agreement to ITER was signed by Europe and Japan, in February 2007, for a first period of ten years. The Agreement comprises 3 projects: IFERC, the International Fusion Energy Research Center, including the Computational Simulation Center, CSC; IFMIF-EVEDA, Engineering Design and Validation of a 14MeV neutrons irradiation facility for material testing and STP, the ITER Satellite Tokamak Program with the JT-60SA project. CEA, in charge of the French commitments, as European Voluntary Contributor Designated by the French government, is participating to these projects, respectively in value for 85%, 33% and 42% of the EU contribution. The purpose of the BA is to support ITER operation and to contribute to DEMO design and studies. This report synthesizes progress and status of CEA contributions to the BA projects. Beyond its BA commitments, CEA is also involved in the development of the JT-60SA Research Plan and in the preparation of its Commissioning and Operation. II) Status of the CEA contribution to IFERC-CSC

II-a) Helios status and upgrade The IFERC objectives are to promote DEMO Design R&D Activities, ITER Remote Experimentation, and to implement a Supercomputer Simulation Centre (CSC) for large scale simulation activities for fusion plasma experimental data analysis, ITER scenarios and performance simulations, and for DEMO Design. The IFERC centre, located at Rokkasho, Japan, is hosting the various IFERC facilities including the CSC. CEA provided the PetaFlops Class “Helios” supercomputer, the associated peripheral equipment and services for 5 years of operation including maintenance. According to schedule, the Helios supercomputer, designed and assembled by Bull Company, entered into operation in January 2012. Helios has a classical architecture with 4410 compute nodes federated by a fat-tree InfiniBand network. Each node contains 16 cores (2 Intel Sandy-Bridge processors with 8 cores each). The total computing power was 1.237 PFlop/s Linpack which yield a 12th place in the June 2012 Top 500 list. At the time, it was the largest supercomputer dedicated to a single scientific community. The Helios architecture was optimised and upgraded by Bull in 2014 on the basis of the feedback of the first two years of operation and following the recommendations made by a dedicated working group of making available for the fusion community additional nodes on Helios equipped with Intel Xeon Phi co-processors (fig.1); with the primary goal of preparing codes to the most promising architecture of future supercomputers. This upgraded has consisted in adding 5 racks equipped with 180 nodes fully integrated to the Helios configuration. Each node includes two Intel Xeon Phi 6110p co-processors (60 cores running at 1 GHz), two Intel Xeon E5-2450 microprocessors (8 cores running at 2.1 GHz) and 48 GB of shared memory in addition to 8 GB of private memory per co-processor. In addition, programming environment tools for Intel Xeon Phi were installed (including Intel tools supporting

2

OpenMP3 and OpenMP4, Allinea DDT and MAP for debugging and optimisation). Moreover 90 additional nodes similar to the ones of the initial configuration were installed. In total, the aggregate peak performance of the Helios supercomputer resulting from these upgrades is 1.982 PFlops (including 0.427 PFlops for the Intel Xeon Phi partition). The Intel Xeon Phi racks were installed on site and accepted in January 2014. The acceptance tests included HP-Linpack for which the performance measured was 225.1 TFlops. The new nodes were opened to user on February 2014. In order to promote the efficient usage of the new Intel Xeon Phi nodes, a set of support actions, supported by Bull and Intel, were undertaken. They include availability of full documentation on the

CSC website, training sessions), monthly webinars on advanced topics including experience on code optimisation, optimisation of “mini-apps” derived from fusion codes. In addition, joint Europe and Japan seminars reporting the experience of Helios users on Intel Xeon Phi are planned in the future. So far, the use of the new nodes is mostly for code porting and optimisation. Their loads should increase when the “native” programming mode of the Intel Xeon will be fully available (end of 2014) and implemented in new generation codes.

II-b) Utilisation of Helios and results Helios is currently used by more than 100 Japanese scientists and more than 300 European scientists. Almost all the users of the CSC are remote, even those in Japan. Allocation of computing resources to user’s project is done by peer review, instituted in a joint setup, the Standing Committee (StC). Proposals are submitted for either

The remaining 10% + 10% are allotted on each party’s specific criteria. With current utilisation of the computer around 85% and reaching regularly 90%, the total resources available for

StC allocation is around 35 million.nodes.hours (about 530 million.cores.hours for a more usual metric). The chosen metrics result from the choice of allocating only one job per node. From the 3rd cycle (table1) a “plateau” is reached for proposal number and job characteristics. It corresponds to a mean size of 0.8 Mnodeh (14Mh) for a proposal. The computation time is still largely dominated by plasma turbulence computation, (fig.2), which has been historically the most compute-hungry discipline. Computation time for other scientific domains is more evenly distributed and shall grow in the future. Along with computation volume, another scientific relevant criterion is the number of papers issued at the end of each cycle. For example, the 2nd cycle results gave rise to the publication of 120 reviewed-papers for the 82 selected projects. The repartition of those papers by scientific domain is more balanced than the allotted computation time and shows the interest for all of them (fig.3). A post-project evaluation is requested by the StC before allocating new project on following cycle. One of the highlights selected this year in the StC Scientific Report was related to the computation of the Density filaments and maximum power flux into the divertor in 7.5MA/2.65T ITER scenario in ELM due to n=12 ballooning mode

Fig.3 repartition per scientific domain of 120 scientific papers written as results of the 2nd computation cycle.

fig.4 Example of JOREK Results

(fig.3) obtained with the JOREK code. Another result obtained with JOREK was related to the Mechanism of mitigation Edge Localized Modes (ELMs) by Resonant Magnetic Perturbations (RMPs) showing that RMPs non-linearly drive tearing-like modes replacing large ELMs crashes by continued MHD turbulence in the pedestal [1]. Aside StC activities for resources allocation and projects assessment the coherence of the remote scientific community of Helios users and operators is ensured by several communications and events: an annual seminar, “scientific” and compute-centric with focus on selected results and challenges, issues and solutions such as large jobs peculiarities in 2013 and on evolution of usage in 2014, a

monthly newsletter for computing news only, a monthly webinar for HPC, helios and new MIC resources training, and an annual “Xeon Phi workshop”, the first held at the Maison de la Simulation in Saclay, France, last May. III) IFMIF-EVEDA activities and results The IFMIF-EVEDA project consists of design and validation activities aimed at providing the intermediate engineering design of the 14-MeV-neutron International Fusion Materials Irradiation Facility and validating the key technologies of the accelerator, lithium target, and test cell facilities. Sharing the work with the Japan Atomic Energy Agency JAEA, INFN Italy, CIEMAT Spain, and SCK•CEN Belgium, CEA is committed in both the validation and the design of the accelerator facility. The 6 years studies of the IFMIF Intermediate Engineering Design were completed by mid-2013 [2] and the report (IIEDR) was adopted by the BA Steering Committee. In this report, details of each of the five IFMIF facilities (Accelerator, Li Target, Test Cells, Post-Irradiation and Examination Facility, Conventional) are defined. CEA was involved in the design of several systems of the accelerator facility (Injector, 40 MeV SRF Linac, HEBT, beam diagnostics), and participated in beam dynamics studies and cost assessment of the IFMIF construction, operation and decommissioning activities. In parallel, validation activities of critical components are progressing and achievements in the prototyping of accelerator sub-systems under CEA responsibility are presented in the next sections.

III-a) Description of Accelerator Facility The IFMIF accelerator facility comprises 2 identical Linacs, each accelerating a cw 125-mA deuteron beam at the final energy of 40 MeV. A total beam power of 2x5MW is required to produce the high flux of neutrons ~1017 n/s through break-up interactions of the D+ beam with the Li target. As the accelerator facility shall reach unprecedented performances, a prototype of the low-energy part of the

4

Accelerator (LIPAc) comprising the injector, the radiofrequency quadrupole (RFQ), the matching section, the superconducting Linac (SRF Linac), and the 9 MeV transport line ended with the beam dump is being developed. Among these accelerator prototyping systems, CEA is in charge of the D+ injector, the cryomodule and cryoplant of the SRF Linac, several beam diagnostics and is involved in the beam dynamics studies, the monitoring of accelerator control system, the procurement of RF power amplifiers as well as in the installation and commissioning of the LIPAc at Rokkasho. This crucial phase, which will be completed after demonstration of the operation of the LIPAc at full power, started in 2013 by the installation at Rokkasho of the D+ injector and will continue with production of its first beams in pulsed mode, expected before end of 2014.

III-b) Beam Dynamics Studies For the design of LIPAC components, taking into account the characteristics of this MW-class beam power accelerator and the threshold of beam losses (1W/m) allowing hands on maintenance, advanced beam dynamic studies were developed [3]. As assessment of adequacy of the human and accelerator protection systems was required too, these studies were performed in every possible beam operation situation that are: start from scratch, beam commissioning or tuning or exploration, routine operation, sudden failure. In a first step, start-to-end simulations, with 106 macroparticles, using input beam results from calculations of the ECR sources extraction system and 3D field map calculated by finite elements for most of LIPAc components, were carried out for 500 different sets of errors randomly distributed over the accelerator components. From the statistical analysis of the results the whole set of static and dynamic tolerances for every component are extracted [4]. In a second step, for each identified operation situation a specific protocol of beam dynamic simulations is applied. The results is a complete 'Catalogue of Losses' [5] allowing the identification of hot spots to be protected for each accelerator component, the definition of parameters, as the beam stop velocity or maximum beam power allowable, for each operation situation. More fundamental studies about the beam quality have also been undertaken, leading to a new approach where the optimization is performed by minimizing the beam halo size rather than the beam emittance, the latter describing mainly the beam core. This required a precise determination of the core-halo limit, obtained thanks to an in depth analysis [6]. With such an approach, risk of losses can be significantly reduced. The next steps will be mainly dedicated to beam commissioning at Rokkasho site of the successive sections of the accelerator until the overall ramp up to final beam power. For preparing these operations, detailed lists of beam tunings and measurements during each beam commissioning phase have been produced.

III-c) SRF Linac Development The LIPAC SRF Linac is a full-scale and operational cryomodule for transporting and accelerating D+ beams from 5 to 9 MeV. The cryomodule (Fig. 5) is a horizontal vacuum tank of ~6 m long which includes: 8 accelerating superconducting half wave resonators (HWRs), working at 175 MHz and at 4.45 K, 8 Power Couplers providing 70 cw kW to the cavities, and 8 Solenoid Packages as focusing elements, provided by CIEMAT. The LIPAc cryomodule design will be used as a reference for the IFMIF cryomodules, once the performance requirements will be experimentally demonstrated after beam operations at Rokkasho. After the design phase of the LIPAc cryomodule, officially ended up by

Fig. 5: General layout of the LIPAc SRF Linac

the end of 2013 with the publication the engineering design report, most of activities are dedicated to the manufacturing of series components. The manufacturer for cavities is selected and the contract ready to be placed. As the HWRs are cooled down by liquid He, they shall be approved by Japanese Authorities before installation at Rokkasho. The licensing procedure of the HWR with the High Pressure Gas Safety Institute of Japan, KHK, is still ongoing. The Power Coupler design was shared in 2 parts: the RF and preliminary thermomechanical design

performed by CEA and then the detailed thermo-mechanical design carried out by the company CPI [7] in accordance with the detailed specification issued by CEA [8]. According to this design, two

5

couplers were fabricated and delivered to CIEMAT [9] for conditioning. Thanks to results qualifying the design and proving its robustness, the manufacturing of the series couplers was launched in June 2014. In parallel, the design of cryomodule components such as vacuum vessel, support frame, thermal screen, magnetic shield, phase separator, cryo-piping, tuning system, etc. was completed. Calls for proposals were issued in 2013 and some of the calls for tender for the critical parts as well. The company for manufacturing the vacuum tank and the thermal shield is selected; manufacturers for remaining components will be selected by the end of 2014. Meanwhile a dedicated test bench was devised. It will allow a full characterization of a jacketed and fully dressed cavity with coupler and tuning system in an environment as close as possible to the nominal operations (without beam), i.e. nominal RF power source, working point around 4K, HWR, coupler and tuner tested in the same position as in the cryomodule. Doing so, the RF, thermal and mechanical behavior of a cavity with its coupler and tuning system will be assessed 15 months before the first RF test of the fully assembled cryomodule, which is a strong mitigation in order to anticipate any problem. First results of this test bench are expected by mid-2015.

III-d) Beam Diagnostics Status Several different types of diagnostics are required for monitoring and driving the LIPAc beam from the RFQ exit (5 MeV) to the beam dump (9 MeV). Among LIPAc beam instrumentation, the CEA is in charge of the beam loss and beam current monitors as well as the transverse beam profilers (Fig.6a), each demanding appropriate development due to the high beam intensity and power, high space charge and radioactive harsh environment [10]. From March 2013 to March 2014, acceptance tests carried out by CEA showed that every diagnostic fulfill requirements. The Beam Loss Monitor is made of LHC-type ionization chambers (IC) [11] providing a signal in less than 10 µs for emergency beam stop. In the energy range of the D+ beam, only gammas and neutrons can escape the beam tube. As ICs are not sensitive detectors at low energy or for neutral particles, very tiny currents of few tens of pA are induced. A specific front-end electronics was necessary, based on integrators for beam monitoring and on discriminators generating a fast signal used to stop the beam. By adjusting the integration time and amplifiers, loss signal can be adapted to the optimal electronic range. This monitor was successfully tested with a 60Co radiation source (Fig. 6b) and a current generator. Transverse beam profile based on ionization of the residual gas by beam particles was developed in a dedicated R&D program [12].

Figure 6: a) HEBT IPM (left) with frame made of 2

degraders, one electrode and one strip plate; b)

Beam Loss Monitors (right) under calibration with a 60

Co radiation source.

Within the area between 2 parallel plates, an electric field is applied which must be kept uniform to provide a linear response. To achieve this key point, degraders with various shapes and potentials were set for improving the electric field homogeneity and uniformity. Moreover, as the beam space charge induces distortions drifting the electron and ions trajectories, measured beam profile is widened. An iterative algorithm is implemented to correct this problem. During the acceptance tests with beam, uniformity of electric field was demonstrated, profile resolution better than 100 µm was achieved and good overlapping of beam profiles for different space charge was obtained with the algorithm.

Industrial Current transformers (CTs) being available, 3 Alternating Current CTs, 1 Direct Current CT and 1 Fast CT have been ordered [13]. Adjustment of the design for the FCT-ACCT pair located at the exit of the RFQ was necessary because available room is small, drowned in a strong quadruple fringe field shielded with soft iron disks. Two Secondary Electron Emission Monitors with 2 grids of thin wires (SEM grids) identical to SPIRAL2 ones [14] were supplied to measure the beamlet passing through 2 perpendicular thin slits (100µm aperture). As consecutive wires are distant from 2 mm, steerers will be installed to increase the resolution allowing measurement of sub-millimeter profile widths by shifting the beamlet position. These diagnostics, including electronics, dedicated tools and cabling were shipped to Rokkasho during August 2014.

IV) Status of the CEA contribution to JT-60SA CEA procurements for JT-60SA include the manufacturing of 9 of the 18 Toroïdal Field, TF, Coils, the supporting structures of the Magnetic Field System, MFS, the Cryogenic System and 5 Superconducting Magnet Power Supplies, SCMPS, as well as the development, construction and operation of a Cold Test Facility, CTF, for the nominal testing of TF Coils. For Cryogenic System and SCMPS, installation, testing and commissioning at the JT-60SA site, Naka, Japan are also part of the CEA commitments. Specification definitions and tendering phases are completed. Industrial contracts have all been placed in between 2011 and 2013 and manufacturing is on-going in Europe. For insuring the compliance between specifications and manufacturing, a Quality Management System based on Configuration Management concepts was developed and applied with industrial partners. CEA also leads for EU the update of the Research Plan [15] and the preparation of the JT-60SA operation.

IV-a) TF Coils, TFC Cold Test Facility, Magnet Structures and Magnet pre-assembly In July 2011, the contract for the TF coils manufacturing was awarded to ALSTOM. For insuring the accurate geometry of the coils, the chosen offer included the manufacturing of the winding pack using rigid jigs and thick impregnation mould, and the use of robots for the welding of coil casings. 2.5 years were needed to the manufacturer for performing the design, the manufacturing and the commissioning of the production line and to develop and validate with the support of CEA the qualification mockups associated to the most critical processes. Since December 2013, the TF coil manufacturing [16, 17] is started and 3 winding packs are being processed. The 1rst coil (Fig.7) will be delivered to the CTF, mid-2015. At Saclay, the setup of the CTF [18] is nearly completed (Fig.8). It will be soon followed by an integrated commissioning including a nominal test at 25.7 kA using a superconducting shunt and a low current quench test using the W7X demo coil, aiming at qualifying the Magnet Safety System. The CTF will be ready beginning 2015. During 2014, the test program and the test procedure were validated. About 2 years are required to perform 18 cold tests. The MFS supporting structures are made of 2 main parts: the 18 Gravity Supports, GS, supporting the total weight of MFS and the Inner and Outer Intercoil Structures, IIS & OIS. OIS is a set of 18 components forming the outer vault of the TF coils assembly. These mechanical structures were optimized to reduce the cold mass and to withstand out-of-plane electromagnetic forces and seismic loads. An R&D

program, including the development of mockups aiming at qualifying the insulated bolted joint of the OIS, the IIS friction joint linking inner legs of TF coils [19] and the sliding coefficient of spherical bearings providing the required GS flexibility was conducted by CEA. In 2013, 2 contracts were placed to SDMS for OIS and to ALSYOM for GS. Both companies validated manufacturing and welding processes on down scale mockups. Now, manufacturing are on-going on time schedules compatible with the JT-60SA assembly. In addition, beginning 2014, CEA agreed to perform at

7

Saclay, the pre-assembly of TF coils with OIS, prior shipment to Naka. Tooling, work area, technical and quality procedures are being developed to be ready mid-2015.

IV-b) Cryogenic System The Cryogenic System shall cool thermal shields at 80 K, HTS current leads at 50K, superconducting magnets at 4.5 K and cryopumps at 3.7 K and shall cope with the large pulsed heat loads generated by plasmas [20,21]. For solving these issues CEA specified an optimized cryogenic concept based on the feedback of a scale down dedicated mock-up operated at Grenoble [22]. In November 2012, the manufacturing contract was awarded to Air Liquide after one year of intense tendering phase with 4 technical rounds and 2 intermediate offers. The solution proposed by Air Liquide uses 4 standard skids of compressors in parallel adapted for helium and equipped with frequency drive for the Warm Compression Station (WCS), a Refrigeration Cold Box (RCB) with 3 turbines and nitrogen precooling and an Auxiliary Cold Box (ACB) with a large liquid thermal buffer

Fig.11 RCB during assembly at Air Liquide workshop

(7 m3 of liquid helium). For the WCS, each skid is composed of 2 compressors whose one equipped with frequency drive which offer flexibility and redundancy. The conceptual and detailed design was validated end 2013. For the main components (WCS, RCB, ACB), the manufacturing is almost finished and tests are planned from August to November 2014 before shipment to Naka. On-site installation and commissioning will start in April 2015 and last 18 months.

IV-c) Magnet Power Supplies, SCMPS: CEA shall procure 2 SCMPS for Equilibrium Field Coils 2 & 5, EF2&5, rated ±1 kV / from -20 kA to +10 kA; 2 for EF3&4 coils, rated ±1 kV / ±20 kA and 1 for the 18 TF coils, rated ±80 V/+25.7 kA. Technical studies performed with F4E and ENEA were used as basis for the detailed specifications for European tendering. The contract was awarded in March 2013 to JEMA Energy Company, located at Lasarte-Oria, Spain, which provided recently power supplies for JET, W7X and MAST. The detailed design for EF3-4 was validated in August 2014 (Fig.12). SCMPS are AC/DC converters based on thy- ristor bridge technology (rectification from 6 to 24 pulses depending on configurations). They are interfaced with re-used installations such as electrical HV grid and transformers and will be connected to a new control system developed by JAEA. The proposal to realize complete functional tests, full power and load tests in JEMA’s factory reduces technical risks during commissioning and acceptance tests in Japan. Furthermore, JEMA-POSEICO consortium is also procuring, for ENEA, the complementary part of the SCMPS (for EF1 & EF6 and Central Solenoid coils CS1 to CS4). This will allow a more homogeneous design and will also ease operation and

maintenance activities. The manufacturing is now launched. Transportation to Japan should occur by the end 2015. The final acceptance of SCMPS is expected 2nd half 2016.

IV-d) JT-60SA Research and Operation plans:

Since 2011, CEA is coordinating the EU contribution to the JT-60SA Research Unit in charge of both periodic update of the Research Plan [15] and managing the scientific collaboration for the preparation of the exploitation. In 2014, the latest activity conducted within the EUROfusion consortium was organized in 3 areas: Modelling, Sub-systems and Operation. For Modelling, CEA provides also the IRFM code suite (CRONOS & METIS) and co-chairs an EU-JA working group aiming at defining the top level requirements for Data Management in synergy with the Remote Experiment Centre (REC) developed within the IFERC project. CEA also joined a working group aiming at defining the

8

integrated commissioning and start-up of JT-60SA and at developing procedures for a safe operation of JT-60SA. V) Summary Every procurement to the BA in charge of CEA was subject to an extensive effort of optimization conducted with the BA partners during the conceptual design phase and of validation and qualification, defined by CEA, both at specification and manufacturing levels. This paper summarized results associated with this quality policy developed by CEA and detailed the achieved performances of the products either already delivered or being manufactured. For IFERC, as expected by the CSC project promoters, the Helios supercomputer became the focal point of a large and productive remote scientific community. Beyond the large number of scientific results already produced, the successful upgrade of Helios, performed by Bull in 2014, including the most up-to-date generation of INTEL processors, is also offering to fusion computation community the opportunity to access the most advanced programming mode for the next generation of HPC. For IFMIF/EVEDA, after the delivery of the D+ injector at Rokkasho, in 2013, CEA completed the development and qualification of a set of high intensity beam diagnostics, as well as the studies of the SRF-Linac and associated Cryoplant. Preparation of the commissioning with beam of the injector, transportation of diagnostics to Rokkasho, tender process for cryoplant and SRF-Linac components are progressing, in such a way that operation at full intensity of the injector, installation of diagnostics on LIPAc and manufacturing of Cryoplant and SRF Cryomodule are expected for 2015. For JT-60SA, a tight follow up managed by CEA allows keeping on tracks every industrial contract. At Belfort, TF winding activities are running at full speed and impregnation activities are on schedule. At Sassenage, the cryogenic system is close to completion and will be shipped to Naka before the end of 2014. At Saclay, the CTF commissioning will started by the middle of fall 2014 with substantial margins regarding the TFC coils deliveries. TFC coil pre-assembly activities were also launched during the summer 2014. At Saint-Romans, industrial qualifications were completed and the manufacturing of the 1rst OIS is in progress, as well as the manufacturing of components for GS assembly at Tarbes. At Lasarte-Oria, manufacturing of the SCMPS for EF3&4 started during summer 2014 and the detailed design for remaining SCMPS is in progress. Beyond its BA commitments, CEA is also actively participating to the preparation of the JT-60SA start-up and operation. The CEA implication in the BA projects represents in the present context a significant and fruitful investment for fusion researches in view of ITER and towards DEMO development.
