CLEX TBM T0 Cooling system Progress Report 1 V. Soldatov, A. Vamvakas, BE-RF

Schematic layout for the CLEX two-beam module cooling CDR cooling layout (Fig ) 2 CLEX TBM phase 3.2 The two phases have different cooling requirements. Phase 3.1: One PETS, one SAS, idle PETS loads Phase 3.2: Two PETS, two SAS The extra cooling circuits for phase 3.2 can be implemented directly or at a later stage

Cooling Scheme 4 At the 02/04/14 CLIC Module Working Group meeting it was decided to use the existing CTF3 cooling network. A mounting rack with all the necessary components will be installed in close proximity to the TBM and the water will be supplied by the CTF3 network.
