9. Engineering Department ENEN BPM cables 24 June 2013A. Dallocchio – EN-MME9  First BPM batch received in 2010; leak tight cables (4 out of 6) used for endurance test on table test bench, to be then re-used for TCSM prototype  16 pre-series TCTP cables received in July 2012 available for 1 proto and 3 series units  Delivery of TCSP cables still pending; expected by 28 th June  Outgassing test strategy for TCSP: 8 cables in one test run; (initial strategy: 4 cables in one test run, to be increased in case of positive results on the first batches)

10. Engineering Department ENEN Action list to complete TCSP assembly 24 June 2013A. Dallocchio – EN-MME10 1.BPM cables reception I.Measurements of the height of shafts shoulder for the positioning of the jaw into the tank (done) II.BPM cables electrical tests (C. Boccard) III.BPM cables outgassing tests (G. Cattenoz) 2.Collimator assembling I.BPM cables assembling on jaws II.Assembling of RF contacts on the top and bottom of the tank III.Assembling of jaws inside the tank and connection of BPM and T cables on the flanges; assembling of flanges + seals 3.Measurements and tests on assembled collimator I.Regulation of end stops and micro switches on 3D machine II.Control of position and flatness tolerances of jaws inside the tank III.Torque test IV.BPM test with antenna (C. Boccard) 4.Further actions before tank closure: 1.Welding of vacuum caps on the axes 2.Positioning of tank cover 3.Torque test before tank welding 5.Tank cover EB welding 6.Tests after welding: I.Leak test II.Outgassing test 7.Delivery to EN/STI; RF contacts in the transitions + limit switch to be assembled by STI

11. Engineering Department ENEN Time schedule 24 June 2013A. Dallocchio – EN-MME11  Delivery of BPM cables by end of June?  After cables reception, at least 10 days needed for electrical + outgassing tests  MME activities (listed in previous slide) take about 4 weeks per collimator  Assembly period right in the middle of summer holidays for most key players!  6 weeks needed by STI to prepare each TCSP for installation  Optimization of the planning will be performed once BPM cables delivery is confirmed
