    PSB Commissioning Meeting #4

    → Europe/Zurich
    Hide
    October 9th 2018
     
    Present: Bettina, Gian Piero, Simon, Fanouria, Vincenzo, Chiara
     
    G.P. merged the two documents prepared by Vincenzo and Bettina (available in EDMS:  https://edms.cern.ch/document/PSB-OTH-NOT-0002/1.2/approvalAndComments
    He also added the information about the beam requested by SPS. Still need to check with Heiko if SFTPRO is really needed for RF setup at the beginning of the run or could be prepared later (only beam using H2).
    Important information to add to the document (Action for everybody): 
    • timeline (when commissioning of four rings) 
    • Which activities and how long each activity will take? (ABT, BI equipment etc.)
    • Pre-requisiti for commissioning of each equipment, which diagnostics is needed at the different stages of the commissioning?
    • Optics measurements (Fanouria will ask Pjotr)
    • Define the operational conditions during commissioning (tune etc.). 
     
    Longitudinal painting: 
    News: longitudinal painting should be tested already this year.
    Still some information missing and a few points to clarify before going ahead with specifications:
    • Present constraints from RF (always start at DeltaE=0, problem with discontinuities): any real limitation for operation? 
    • Effect when requesting different number of injection turns per ring (not possible having different RF modulation per ring)
    • When is longitudinal painting absolutely needed (number of turns)
     
    Next meeting in two weeks.
    There are minutes attached to this event. Show them.
