2 Scope BOSS mini-workshop 27/05/2014 2  Overview of beam instruments  Installed in PSB injection line (BI line)  Installed in PSB rings (BR)  Installed in PSB extraction lines (BT, BTP, BTM, BTY)  Operational/development/obsolete  Criticality  Other issues  Beam instrumentation to be installed for the PSB upgrade (LIU-PSB) not mentioned here

3 PSB Injection BOSS mini-workshop 27/05/2014 3  Splitting into 4 PSB rings downstream of BI.SMV10  (synoptics still to be updated for naming changes…)  LT+LTB lines are under Linac2 responsibility

18 Conclusions 278 BI equipment currently installed in PSB complex (187 without BLMs) Practically all installed instruments in the PSB are critical for operation. Many instrument modifications (equipment + electronics + software) during LS1. New instruments for LS2. Instruments in layout DB except for BTY line and certain BLMs; will follow Optics have been updated Positions are currently being corrected in layout DB GEODE will be updated with new names BOSS mini-workshop 27/05/2014 18

19 Beam off BRr.BCTDC9L1: beam intensity in the rings; also used for ISOLDE+EAST beams intensity interlock BRr.BCW8L1: essential for bunch synchronisation BRr.BPTF4L5: no high intensity beams in case of failure BPMs in extraction lines: failure of 1 can be worked around short-term, but need to compensate with others (recombination and bunch spacing) BCTs in extraction lines: failure of 1 can be worked around short-term, but need to compensate with others BLMs in extraction lines: could probably live a few days with one broken (would need to be removed from interlock!)
