SAD and Summer Run Schedule
Pre-Beam Jobs
  • PQB screen shots of control screens - https://logbooks.jlab.org/entry/3681125
  • Laser configuration (ABCD)
  • Helicity board configuration
  • PQB laser configuration
  • Activate photocathode & QE scan
  • Configure for anode bias
Beam Jobs to FC#1
  • Pick all save for restoration, move to new spot, restore orbit
  • Set photocathode rotation (few access to roll puck, then PQB measurement to where? to finalize orientation)
  • Study and then fix anode bias for 0V, 500V, 1000V (TOF using chopper, beam size or emittance scan using solenoids)
  • ABC transmission setup w/ which? flipper choice (either makes transverse polarization) + HWien ~ 16 deg.
  • What PQB beam measurements to make?
Beam Jobs to FC#2
  • Initial restoration to FC#2
  • Carry on w/ ABC setup (finalize flipper choice here, maybe?)
  • Mott measurement to precisely finalize spin rotators (VWien and Solenoids)
  • Iterate w/ ABC setup, to FC#2
  • What PQB beam measurements to FC2 (can be high current)
Beam Jobs to ILD, and beyond...
  • Initial restoration to ILD
  • Scaling RF and injector magnets, energy/injector beam setup
  • Complete ABC setup to ILD
  • M56/PQB measurement to ILD?
Beam to Halls
  • What is prioritize/sequence for jobs, e.g. when does spin dance happen?
Punchlist
  • FC2 air cylinder needs to be replaced
  • Regular RTP rise time procedure (how often?, as-is manual or automated?)
  • Insertable lens (is alarm sufficient, or disconnect IN/OUT control?)
