LIU-PSB Milestones LS1: 1.5 year Half Sector Test −connection of PIMS12 to be completed on 22 nd June 2016 (J. Coupard, ) −Part 1: L4T Q  Q −Part 2 : HTS Q  Q EYETS = Extended-Year-End Technical Stop −16 weeks, from Dec to March 2017 −All WPs related to Linac4 connection: end 2016, should LHC fail all of a sudden. LS2 −1.5 year, from Q to Q −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
