Low Pressure drop over long distances requires large pumping headers !


Alternative Configuration Distributed 2 K refrigeration

•Increase the distance between cryoplant by a factor 2

•Require specific alcove for 2K cryoplants but saving of a lot civil engineering and infrastructure as well as reducing of the surface site impact.

•Require specific study on the design and operation of “underground” warm compressor station

•Require refrigeration (water) capacity of about 1 to 2 MW per alcove

•Require an additional header in the cryomodule to return the compressed He (20-30 K, few bar) to the main cryoplant

Alternative Configuration Larger cryoplants

•4.5 K refrigerator•Feasibility study on larger refrigerators (40-50 kW

equivalent at 4.5 K) and impacts on cost, layout, operation, site …

•R&D requirement

•Warm centrifugal compressor as booster•Feasibility study with impacts on cost, operation and

reliability.•Validation test is mandatory.

•2 K refrigeration•Feasibility study on larger cold compressors and

impacts on cost, layout, operation…•R&D requirement


Alternative Configuration Cryomodule

•Cryostat optimization•Cost effectiveness of the 5-8 K shield•Use of conduction cooled current leads for quadrupole (if

HTS retained as baseline). Gain on operation flexibility.

•Separated distribution line•Mainly justified by cost saving, if any (no sectorization

required for cryomodule repair or exchange).•Could be interesting in case of 2 tunnels (operation

availability if the line is in the service tunnel)•Could increase the filling factor of the linacs•Could be justified if the vibration due to He flow is not

acceptable (reduced flows in cryomodules).•Could simplified the heat intercept design and efficiency

(small pipe can be routed close to the components to be thermalized)

•The 300 mm pumping header (thickness 6 mm !!) is use as a rigid beam for cavity alignment inside a module (separated line with or without the pumping header?)

1. Executive Summary The current planning phase of the CLEX area at CTF3 has revealed an excellent opportunity to build a flexible Instrumentation Test Beam (ITB), at a time when such a facility is in high demand and short supply, to address both ILC and CLIC instrumentation issues. This proposal addresses some preliminary baseline requirements of the ITB, presents initial cost estimates and timelines, and identifies some key diagnostics tests that could be addressed. 2. Introduction The CLEX layout is presented in Fig. 1.
