LIU-PSB Milestones LS1: 1.5 year Half Sector Test −Part 1: L4T  Q −Part 2 : HST  Q EYETS = Extended-Year-End Technical Stop −16 weeks, from Dec to March 2017 −All WPs related to Linac4 connection: end 2016, should ● Linac2 fail all of a sudden. ● LHC experience a major problem LS2 for the PSB −Upgrade: 15.5 months, from 07 January 2018 to 16 April 2019 −All WPs related to PSB energy upgrade −Linac4 connection to PSB if not done during EYETS Presently there is no management decision to relax on the end-2016 deadline for the Linac4 connection to the PSB. Therefore this has to stay the baseline for our planning. 5

Upgrade of BPMs in BTM & BTP extraction lines −8 monitors + 2 spares −New front and back end electronics for compatibility with Linac4 beams −New lab test bench −Budget : 264 kCHF −COMPLETE 6 Work Units completed during LS1 BTP.BPM10
