Current Status

• Taking the beam we can get!

Current Run Plan

• Finish off the two HeepCoin settings
  • Unfortunately, we will need to redo the first setting - https://logbooks.jlab.org/entry/3903149
• Start the first Physics setting!
• We will need Amy/Steve L to monitor a rotation in a few hours (~1900-2000 this evening)
• Tentatively, we may need a hall access tomorrow late day or early swing for SHMS rotation to 6.26, we will see how physics goes overnight
  • If we are lucky, we could utilise the ~1 hour down we will have tomorrow to do this rotation

Planned Accesses to the Hall

• Joe B and Larry both requested an access when possible
  • See Hall Status, will drop to controlled during Hall D setup

Accelerator Status

• Not much beam yesterday due to accelerator work and storms
• Downtime for Hall D related work shunted to Monday next week
  • Expect ~1 hour downtime tomorrow related to this though

Hall Status

• CODA issues this morning, no SHMS triggers
  • CODA relatively unstable overnight too
  • Resolved this morning, crate had to be reset - https://logbooks.jlab.org/entry/3903101
• SHMS Hodoscope HV issue, getting intermittent high voltage alarms
  • Power cycled crate 14, this improved things a little
  • Card had to be replaced, no alarms since - https://logbooks.jlab.org/entry/3903170
  • Some runs after the cycling/replacement may be usable, will need more careful analysis offline - https://logbooks.jlab.org/entry/3903193
