  2. Issues:
    • Solenoid dump at 11:30 am
      • Traced to defective Convectron panel meter [1]
      • Started ramp back up at 14:33

      • DAQ computer acting weird, but this did not impact actual data taking
      • Alcohol bubbler too dark to see: [4]
  3. Plan:
    • Continue production at 150nA on diamond
    • Saturday day: Low current + empty target?
    • Saturday swing: switch to liquid deuterium
  4. Analysis update

      • Repair plan: down at ~10 am for ~30 minutes, then acc will decide if full system needs to be down for repair for longer time
      • Some discussion regarding using magnetic separation for 1 hall running if down more than 30 minutes
  2. Issues:
    • writing on tape?
    • High temperature of locked-up FCAL bases? [6]
    • Shift crew will take over servicing FCAL base lock ups. wiki instructions
