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

  • None

Planned Accelerator Configuration Changes

  • Thursday, Nov 15: system recovery, spot move, 2L13 maintenance, 5th pass horizontal separator work
  • Tuesday, Nov 20: CHL UPS battery change, should be noninvasive however, induce CHL anomaly is possible
  • Wednesday, Nov 21: 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.

Special Requests

  • Jay B. Would like to conduct another beam steering test (5 minute procedure) during the next polarity change. He requests to only be contacted if the polarity change occurs during the hours of 0630 and 1930.
  • Brad S. would like to investigate HMS trigger components during the next long down (assuming it is during the day)
  • Carlos Munoz Camacho would like access to the hall to show Hall-C to two French engineers working on the NPS project. It should be a ~30 minute access, and is a low priority. He can be contacted at 357-1065
