  • Good - Run 6633
  • Good - Run 6636
    • An outlier in bcm_asym (~8000ppm)
  • Good - Run 6637
    • Some energy excursion (~1mm)
  • Good - Run 6638
  • Good - Run 6639
    • LHRS yield started degrading again
  • Good - Run 6644
    • Septum needed to cycle before this run.
    • LHRS energy slope jumped up after the cycle
  • Good - Run 6645
    • ~-5+/-3ppm Aq in minirun3
  • Good - Run 6646
  • Good - Run 6647
    • ~1mm of energy bpm excursion
    • dpp jumped to ~-3e-4 causing ~3mm of less acceptance in quartz.(See https://logbooks.jlab.org/entry/3790948)
    • This caused energy slope increase and width increase during minirun4
    • Applied bad_event_cut for CodaEventNumber(351000:354000)
  • Good - Run 6650
    • MCC sent ~25uA unrastered beam accidentally for about 40sec just before Moller measurements
    • This run was dedicated to test target performance
  • Good - Run 6662
    • BCM widths are slightly larger starting this run
    • When we come back fro Moller measurement, Energy slope, detector widths and yield get worse and remain stable there
  • Good - Run 6663
  • Good - Run 6664
