LSC - 28 February M. Pezzetti – Cryogenics 3 Last 09 April 2013 TE/TM meeting :

LSC - 28 February M. Pezzetti – Cryogenics 4 QURC R2E project overview: P4 high priority, to be done during LS1. ICL  positioning validation P4 equipment inventory, very short time! ( ECR (edms ) driven by cryogenic but all group involved R2E/P4 Planning (w.r.t LS1 planning) EN/EL (DIC : 350 cables) Special cable magnet bearing assembly ( Magnet Bearing electronics MBC170 (prototype validated, ordered, production delivery March 2014) RadWG (new w.r.t TETM of april’13)  valve positioner & I/O cards ( (ordered, in production delivery beginning April 2014) Cryo RF relocation (development, construction & installation May/June) AMB special cable FINAL length = 45 meters

LSC - 28 February M. Pezzetti – Cryogenics 5 Cryo cabinet relocation (Cable length 45m) [UX45 – level 2] QURC [8 cabinet QURC (AMB, Drive, local PLC & 45 SIPART positioner ] [US45 - level 1] QUI[1 cabinet (PROFIBUS & 20 SIPART positioner)] [UX45 – level 1] QURC a-b[2 cabinet (PLC, PROFIBUS)] [UX45 – level 0] Cryo RF[4 cabinet (PROFIBUS & 20 SIPART positioner)] TOTAL 15 cabinets to be redesign and relocated in UL44/46. R2E P4 relocation to be done in LS1

LSC - 28 February M. Pezzetti – Cryogenics 9 Main personnel resources Electrical work TE-CRG-CE: 1 staff (B. Ivens) + 4 FSU EN-EL CABLING: CEGELEC + 1 staff / 1 FSU Magnetic bearing elect.: being defined, estimated 1 engineer + 1 technician. Approx. 10 persons involved for the main tasks (during 3-4 months).

LSC - 28 February M. Pezzetti – Cryogenics 10 R2E P4 budget status (budget code 99547) TE/CRG cabling manufacturing 75 kCHF (old figures 50 kCHF) new! New AMB MECOS electronics (R&D + prod.) 150 kCHF (30 kCHF 2013 / 120 kCHF 2014) EN/EL cabling 250 kCHF, 2014 budget (to be validated by EN/EL) new! new SIPART 250 (Ph1 cabling (20 kCHF 2014)- Ph2 installation (230 kCHF 2015 or later) new! AMB Commissioning 20 kCHF/ 2014 budget new! RF + Others 100 kCHF (HW + FSU manpower) new! TOTAL ~800 kCHF To be compared R2E/P8 budget was 700 KCHF (without RF relocation). S. Claudet courtesy

LSC - 28 February M. Pezzetti – Cryogenics 11 QURC R2E project overview: P8 low priority, LS2. stand by, Ph1 : ICL (already done!) and EN/EL DIC identification w.r.t technical solution as equal to P4. Cold compressor Special cables (already bought!) 75 kCHF. R2E condition don’t change until LS2. P6 low-low priority, LS2. Stand by, preparation activities for Ph1 will start this years with ICL, P6 equipment inventory and DIC identification. R2E condition measurement in 2015/2016. P6 no R2E mitigation need. US85 level 0

LSC - 28 February M. Pezzetti – Cryogenics 12 Conclusion No show stopper identified. Integration P4-P8 approved, P4 equipment inventory done, ECR release (February), planning agreed with LS1 coordination, new magnetic bearing electronic prototype validated, special cables ready (10 March MECOS validation at CERN). P4 DIC (Demande Installation Cables) approved/scheduled by EN/EL. Next steps Cabling & installation (from March 2014 to end of June, no margin). Special cable fragile  Close supervision during cabling campaign. Tight timeline & intense co-activities between cabling, cryo technical and maintenance. -> need a close technical supervision/coordination follow-up.
