Past 24 hours

• HARP scan results
• No beam between 9am and 12am (beam came back at midnight)
• CCAL transported to experimental hall and fixed to its platform by Scot and his team

Shift Reports

• [ 0400-1000]
• [ 2200-0400]
• 1600-2200
• 1000-1600
• 0400-1000

Reports

• Hall D survey (Moser/RadCon)
• CDC HVB current vs HV for 250nA HV scan runs on 4.5E-4RL Al on 17 Jan 2023 (Naomi)
• gluon100 rebooted PS/PSC scalers are visible (Sergey)
  • Sasha also power cycled PS/PSC crates
• Statistics balance
  • PARA 0/90: 20.7%
  • PERP 0/90: 20.2%
  • PARA 45/135: 21.1%
  • PERP 45/135: 19.7%
  • AMO : 18.3%

Issues

• TAGM discriminator TRG scaler gone wild

Pending:

• Start Counter (Beni) - We do not understand why there is a mismatch in the software between start counter and tracking.
• BCM calibration. Alexandre recommends that we request a recalibration of AD00C BCM.

Plans

• Install CCAL whenever there is an extended accelerator downtime
  • Restricted Access is needed to be able to use the ramp <-done
  • Cabling
  • Survey is needed
• Production (300 nA, 2h runs) with cycle:
  • 2 runs PARA (0/90)
  • 2 runs PERP (0/90)
  • 2 runs PARA (45/135)
  • 2 runs PERP (45/135)
  • 1 run AMO (use it to rejuvenate AMO reference in CBREM EPICS GUI)
