Lab Modules

• Status– 1st module T0 under tests (see next slides)

• Different steps defined (according to variation of tunnel air conditions and power dissipation from components).

• Cooling system and heating system working as expected.

– 2nd module T0 under fabrication/assembly – module T1: main components (e.g. girder, RF

structures) under procurement– module T4: girders and DBQ available, note the

few components needed

CLEX Modules

• Status– 1st module T0 [installation shut-down 2014]

• 2D layout defined • RF system: under fabrication, disks at CERN, 1st

PETS unit at CERN• Supporting/positioning system: contract to

ZTS/Boostec for the 3 modules. Set for 1st module in August.

• DBQ: available– 2nd module T0 [assembly from 2014]

• RF system: waiting for validation of 1st module T0 (this is the most costly part)

• Supporting/positioning system: note the need of validation of interconnection and articulation point before installation in CLEX

– module T1 • Supporting/positioning system: see above

Summary • Lab Modules

– Components available at CERN or under procurement– Experience from previous modules injected in the design for future modules– Real components allows for a better understanding of the module behavior– T1 lab: a real SAS will be installed (in a second assembly iteration)– Program runs until mid 2015 – T4: no RF structures, girders/Q available

• CLEX Modules– Integrated supporting/positioning system under procurement– RF system for 1st module under assembly– RF system for following modules: validation of the first module prior to new call for tender

• Reviews– “ Committee” from Nov 2013 for about 1.5 years – Mandate, three action lines to consider, within and agreed resource plan:

• Lab: program optimization• CTF3: strategy for 2nd T0 and T1• Definition of next module generation (based on lab/CLEX results industrialization study, re-

baselining) – Main subjects for first review: Lab thermal test and CLEX test preparation
