Current Run Plan

Notices in Effect for Shift Crew

  • Shift leaders, please fill out the check list once per shift!
  • It is no longer required to fill out the standard.kinematics file online, it is now done automagically
  • Split the large desired charge between multiple runs (~1 hour per run)
  • Listed currents are estimates. For runs at less than 60uA, increase current until SHMS singles rates are between 400k-500k.
  • How-to power cycle PLC I/O chassis: https://logbooks.jlab.org/entry/3625862, https://logbooks.jlab.org/entry/3625900

Current Issues

Planned Accesses to the Hall

  • Monday, Nov 26: aerogel change and HGC work needs to be coordinated with Walter K., we must be in restricted access for this work

Planned Accelerator Configuration Changes

  • Sunday, Nov 25(?): Hall A goes offline and MCC wants to conduct high current beam study of energy spread at 40 uA. It is unclear that we will be effected
  • Monday, Nov 26: Energy change to 1.86 GeV/pass, we will be moved over to 500 MHz laser.
