Agenda/Notes

  1. Review staffing for shifts - still light on Saturday shift 2 


    		FridaySaturday
    Shift 1 (6p-1a)Philip, Dionisio, Kaz, Lorenzo, Alex (remote), XavierBhavna, Philip, Julian, Bojan, Xavier
    Shift 2 (11p-6a)Bhavna, Zongde, Julian, Bojan, Dionisio (tentative), Alex (remote) 

    Kaz, Zongde, Alex (remote) 

  2. Analysis scripts
    1. need runs at MFX/RIX to test scripts properly, Alex to take that data
  3. Some concern about noise in the HR, based on what Philiph/Zongde have seen in single photon data 
  4. What we need to do and check during bedtime
    1. Pedestal scan:
      1. Check pedestal noise
      2. Check temperature stability – nominal temp and stability
    2. Linearity scan:
      1. Check switching point
      2. Check residuals
      3. Gain ratio between high/medium/low
    3. Flat field:
      1. SNR for single photon
  5. Analysis bookkeeping:
    1. Maybe shared slides to throw plots into and keep everyone update in realtime and to declutter slack
    2. If there's enough personnel on a shift, have someone take notes of discussions of what we're seeing

Resources for beamtime

Grafana page to monitor HR in MFX/RIX

Grafana page to monitor DAQ (# of damaged events, etc)

(Kaz's) beamtime run notes for Feb shifts: /sdf/home/n/nakahara/analysis/detectors/IH/epixhr_20240216

G-drive folder for data analysis results and notes

Data-taking scripts (all same as before?)

  1. seq_epixhr --rate RATE --daq subharmonic_division --tgt TGT
    1. e.g. seq_epixhr --rate 5160 --daq 2 --tgt 0.834e-3
      1. This would be runrate=5160, daqrate=5160/2
      2. --tgt may not be needed.
  2. epixhr_timing_scan --linear START STOP STEPSIZE --events EVT_PER_STEP --record
    1. e.g. pixhr_timing_scan --linear 2000 40000 1000 --events 1000 --record 1
  3. start_ns default location same as before?  (24000?)
  4. epixhr_pedestal_scan --record 1 --event 8000 (start with FH)
