Power supply • “New” solution for power supply – Discovered at dismantling of the West Area (WA) • Decommissioned, needs refurbishment • delivers 704 V, 7200 A – capabilities are well above the ones of the ALICE type and therefore can easily serve the demands of the experiment • Refurbishment: – 100 k. Ch. F (Alice purchase 300 k. Ch. F) – installed/operational without cables • Reuse in Japan not excluded – needs communication with DG • oil-filled transformers, not to be placed inside, next to building 193 – DC cables 15 k. Ch. F more expensive video 7. Dec. 2004 A. Fabich, CERN 2

committees RPC • People interested RB • no exceptional questions • Failure of communication • A few open questions – – – is this a US proposal; who is in charge (spokesperson) for the experiment; who is the CERN contact person; why is mercury chosen; what resources are required, eg. cryo, power supply etc. , manpower … • Conditional approval • Clarifying meeting soon, called by the department leader video 7.
