RC meeting and Run Plan, Tuesday February 21th

RC Report

• https://logbooks.jlab.org/entry/4135876
• RC: Bogdan Wojtsekhowski, bogdanw@jlab.org

Summary

• Beam delivery is as usual
• We had ~45 uA beam some times
• Total charge collected over last three shifts is just 0.9C

Issues

• Average beam current is on the level of 1/3 of projected 45 uA

Current Status

• Production on He-3 target when beam is available

Run Plan

• Continue running 45 uA on He3
• Accelerator will prioritize beam and not have any maintenance days this week

Data Collection and Polarization Status

• 38.6C of uncorrected charge for this kinematic (44.0C of corrected charge which is 28% of the plan)
• Last NMR 51%

Other Topics/Status Updates

• 8 Target Operator Shifts need to be taken
• Readiness for Monday 3/27 target replacement
• Moller polarimeter readiness for 3/28 run

Requested Accesses to the Hall

• Holly need access related to SBS GEM electronics
