Design and Optimization

• Understanding of the Geology, Geography and natural environment is extremely essential requirements for civil engineering design.

• Natural Bedrock itself will be the tunnel structure in NATM tunneling.Grasp of the detailed bedrock properties is the most important item.

• 3D Design Integration with the Geology, Geography & Accelerator Lattice is needed to optimize the underground facilities layout

Electric Power Infrastructure

Electric Power Demand of the ILC operation is about 1.5 % of the total Supply Capacity of Tohoku region (6 Prefectures)

The current supply reserve capacity maintains over 10%.

Electricity demand of the Tohoku districtslightly has more winter than summer.

Outline of the Change Request Extension of Main Linac Tunnel:• Both the Electron and Positron ML Tunnels by approximately 1.5 km. • Electron Linac Length: 12.3km →13.8 km, • Positron Linac Lebgth: 12.2 km → 13.7 km

Rational: • Adjust the total beam-line path length on the Positron side in order to fulfill the

timing constraint by the baseline method of positron production

Main Discussion Points

• No Cryogen storage underground for CFS safety reason• Shorter 2K transfer line for effective cryogen transport• Radio-activation of helium during long-term operation• Easier access for helium and liquid nitrogen supplies from companies • Noise and mechanical vibration from compressors and cooling towers• Helium inventory during long-term shutdown• High pressure gas safety code

TOT carries out :• Data analytics to create a set of summary

outputs and visual decision aids.• Series of analytics to give a range of

Optimum Access tunnel positions onto a fixed LINAC position

From the report/John Osborne(CERN) in FCC-Week 2015

Reference: TOT on the FCC ProjectTOT Development on the ILC CFS

TOT: Tunnel Optimization Tool

User defined Input : • ILC main alignment information and

access tunnel positions in 3D space.• Sets of Requirements for Access tunnel/

portal locations to achieve

Status of Contract: CERN & KEK• On going the contract procedure

next steps


ILC & TOT

CERN & Arup will work with KEK & ILC to upgrade and adapt the Tunnel Optimisation Tool to provide the same benefits for the ILC tunnel that have been brought to the FCC feasibility study

From the CERN-GS Report of FCC Week 2015 at Washington

ILC PAC Meeting @LAL Orsay

CFS Plans for work over the Upcoming 6 months

• Optimization of Horizontal Access Tunnels (CR-03 & 04)• Geological Investigation at IP area in new baseline

- with in-kind regional contribution by Tohoku Univ. and Iwate Prefecture

• CFS Workshop in July 2015 (London or CERN)- Cooperative work with CERN and ARUP for preparing for

the layout optimization software. - Global discussion of Cryogenics scheme change

Response of the Future Change Requests

• Revision of Main Linac Tunnel Configuration (ML Length and Radiation Shield-wall thickness impact )

• Revision of the BDS Tunnel configuration• Revision of the Utility Cavern with Cryogenics scheme change
