Topic for discussion

https://logbooks.jlab.org/entry/4247080  Ops cycled the Hall B dipole string with beam to Hall C, disturbing C orbit.  Ops should be advised that cycling LAM1C, LAM3C and BSY[123]C should be done with beam off to all halls until further notice.  A test should be run cycling BSY3C while there is beam to the Hall B tagger yoke to determine if the C string affects B.  110881 below

Beam studies start 0830

    1. 30-40 minutes for rfcal of ten SL cavities to finish up that linac.  https://tasklists.jlab.org/bslist/tasks/22480 beam to 2R
    2. one hour https://tasklists.jlab.org/bslist/tasks/110689 debug scl .  FC1
    3. one hour or more Alicia  https://tasklists.jlab.org/bslist/tasks/110757  inline dump
    4. one hour Injector bunch length measurement Yan 
    5. 30 minutes https://tasklists.jlab.org/bslist/tasks/109612 use NDX to find 2L22/2L23 cavity causing high neutron dose at 2L23 NDX https://logbooks.jlab.org/entry/4248536 
    6. low impact RF maintenance work at C100s e.g. contact cleaning, in parallel with injector work
    7. investigate KMAI zero readings in one SL C100 zone 
    8. arc 1 bunch length measurement Brian 
    9. if submitted, SWList follow-up to https://tasklists.jlab.org/swlist/tasks/110765 which leaves the KPOWLIM values in CED 
       Start beam restoration to halls no later than 1400 for further beam studies
    10. https://tasklists.jlab.org/bslist/tasks/110881 Do Hall C or Hall A dipole strings affect B beam? Bequires B in Beam Permit and C in Power or Beam Permit
    11. beam tuning to improve current capability to C, general cleanup and training

February 21 beam study options

    1. Download of SL gradient calibration values with subsequent E01 matching as required
    2. High current (80 uA) test to Hall C dump.
