4. ATS-PM-MS-0001 Version 1.1 → 2015-10-13 Length of YETS 2015-2016 / EYETS 2016-2017 J. Coupard, D. Hay, D. McFarlane, S. Mataguez This is a proposal for the Year-End Technical Stops and the Extended Year-End Technical Stops before the Long Shutdown 2. It defines the length of the Technical Stops in the PS, PSB, SPS and LHC accelerators. Start and end dates of the YETS and EYETS might evolve in time, but lengths need to remain unchanged. 2015-08-26S. Chemli for EN-MEF-DC4 Master Schedule Under Approval

13. CT-PPS CMS-TOTEM Precision Proton Spectrometer Cerenkov Quartic timing detectors (cylindrical Roman Pots, 220m region, sector 4-5 and 5-6) & associated components – start: YETS 2015/2016 -> TS 2016 – ECR under preparation Pixel detector (horizontal RPs, 210m near/far, sector 4-5 and 5-6) & associated components – start: YETS 2015/2016 -> TS 2016 – ECR under preparation Clock distribution system - based on rigid RF cable to be laid from 220m region sector 4-5 via the bypass to 220m region of sector 5-6. – start: YETS 2015/2016 – ECR draft version already in EDMS (Finn Rebassoo) – First meeting with G. Canale (EN-MEF) took place last week 16.9.2015 -> problems with the size of the cable drum -> not yet clear how to proceed. Already referenced as LHC-XRP-EC-0012 From M.
