Monday February 20

Past 72 hours

• Production runs. ABU = 35.5 h for the weekend. (12.7 h Friday, 13.8 h Saturday, 9.0 h Sunday)

Shift Reports Friday

• Day shift summary
• Swing shift summary
• Owl shift summary
• Early Riser shift summary

Shift Reports Saturday

• Day shift summary
• Swing shift summary
• Owl shift summary
• Early Riser shift summary

Shift Reports Sunday

• Day shift summary
• Swing shift summary
• Owl shift summary
• Early Riser shift summary

Reports

• Hall A fire alarm on Sat.
• Temperature rise of target compressor cooling water (Tim)
• TAGH hot channels w/ no beam
• Harp scan on Friday
• Noise in FDC2 (Lubomir)
• FCAL11 crate problems (Sergey)
• For production runs please try to start the DAQ with beam on (Naomi)
• Tagger cycled (Alexandre)
• Statistics balance
  • PARA 0/90: 21.4%
  • PERP 0/90: 20.7%
  • PARA 45/135: 20.7%
  • PERP 45/135: 20.4%
  • AMO : 16.8%

Issues

• BCAL (Mark)
  • ISEG channel measured voltage has ripple
  • ISEG replacement module has bad channel
  • BCAL has been at wrong temperature since Thursday

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. (~30 mins?)

Plans

• BCM calibration from 10:00am (takes ~2h). Cannot access the hall during this task. Good time for BCAL cosmic runs?
• 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)

Friday February 17

Past 24 hours

• Mark D. replaced the bad BCAL HV board with a new one at 9:40am.
• No beam from 13:00 to 17:30 (0L40 cryo issue). Several people worked in the hall during this downtime.
• Production runs resumed after beam came back.

Shift Reports

• 0400-1000
• 2200-0400
• 1600-2200
• 1000-1600
• 0400-1000

Reports

• Please don't prestart very early (for CDC calibration) (Naomi)
• Broken TAGM scaler issue resolved (Hovanes)
• BCAL HV board changed [1] [2] (Mark)
• Several works done in the hall during day-shift downtime
  • IOC for chiller issue --> Fixed by Josh, Scot, and Bobb.
  • BCAL chiller alarm --> Fixed by Hovanes.
  • DIRC FPGA communication errors, DAQ issues (not communicating with most of ROCs) --> Fixed by Sergey.
  • Sasha and Vlad entered the hall for the calorimeter work.
• Higher occupancy in FDC -> Efficiency looks OK. (Lubomir)
• Statistics balance
  • PARA 0/90: 20.8%
  • PERP 0/90: 20.0%
  • PARA 45/135: 21.1%
  • PERP 45/135: 20.7%
  • AMO : 17.3%

Issues

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. (~30 mins?)

Plans

• On Monday, Sasha and Chris are planning to work in the hall (?)
• 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)

Thursday February 16

Past 24 hours

• Production runs with a stable beam.
• 2 BCAL HVs have been off since midnight due to a bad voltage board.

Shift Reports

• 0400-1000
• 2200-0400
• 1600-2200
• 1000-1600
• 0400-1000

Reports

• Rebooting NMR meter and its IOC (Hovanes)
• target LCW temperature alarm (Alexandre)
• Noise on some TPOL channels (Data should be good enough). (Michael Dugger, Beni)
• Statistics balance
  • PARA 0/90: 20.9%
  • PERP 0/90: 19.9%
  • PARA 45/135: 20.8%
  • PERP 45/135: 20.4%
  • AMO : 18.1%

Issues
