• FADC Window Check (expert only: [Link])
• Begin Kin2 (always use PS1=PS2=PS3=1 (unless otherwise specified))
  • Carbon Hole centering check
  • Home, 10uA, 10 minutes
  • multifoil, 10 uA, 10 minutes
  • carbon, 20 uA, 10 minutes
  • carbon, 20 uA, only PS8=100, 5 minutes
  • Empty Cell, 20uA, 30 minutes
  • 3He Cell, 20uA, 1hr 40min
  • 1H Cell, 20uA, 40min
  • 2H Cell, 20uA, 40min
  • 3H Cell, 1hr 20min
  • Empty Cell, 20uA, 30 minutes
  • 3He Cell, 20uA, 1hr 40min
  • 1H Cell, 20uA, 40min
  • 2H Cell, 20uA, 40min
  • 3H Cell, 1hr 20min

Jan 13 Day

• Carbon Hole centering (with Meekins adjusting encoder values)
• Check distance from centered on hole to collimator edge, change only BPMBx (should be nearby in positive BPMx)
• Raster size fine tuning
• Harp scan with raster on (clock trigger only)
• BPM pedestal run (Call in Jason)
• Bullseye scan (with Jason)
• Trigger checkout (Florian looking a remote scopes)
• Prescale/deadtime checks with dummy target
• DAQ checkout (shifters/experts check online plots)
• optics data:
  • Single-Foil Carbon, raster off
  • Single-Foil Carbon, raster on
  • Multi-Foil Carbon, raster off
  • Multi-Foil Carbon, raster on
• If still waiting for gas cell permission:
  • Dummy Target, 10uA, raster on

Jan 12 Swing

• Hall Access --Completed
• Collimator edge-finding --completed
• clock run for BPM sanity check
• Bogdan's raster target edge-finding sanity check
• carbon hole finding/centering (see how close we can get, may need to ask for BPMBx != BPMAx in order to avoid collimator)
• Continue with the Commissioning Plan: [1]
  • Do not skip the bullseye scan (even though we took one harp scan earlier today)
  • Doug will do the Arc energy measurement sometime this weekend. (Don't call him for this in the middle of the night...)
• If startup procedure is completed, take 5uA runs, 30 min each:
  • Single-Foil Carbon, raster off
  • Single-Foil Carbon, raster on
  • Multi-Foil Carbon, raster off
  • Multi-Foil Carbon, raster on
• If still waiting for gas cell permission:
  • Dummy Target, 10uA, raster on

Jan 12 Owl

• Follow Startup Procedure: https://wiki.jlab.org/tegwiki/index.php/Additional_Installation_and_Commissioning
• HALOG EVERYTHING
• If startup procedure is completed, take 5uA runs, 30 min each:
  • Single-Foil Carbon, raster off
  • Single-Foil Carbon, raster at nominal
  • Multi-Foil Carbon, raster off
  • Multi-Foil Carbon, raster at Nominal

Jan 11 Swing

• Monitor the target
• Check that RHRS and LHRS are at 15.577deg and 3.1 GeV
• Take Cosmics on both arms until beam setup begins
• coordinate with MCC for 5th pass beam setup!

Dec 16 Owl Shift

• Finish the Boiling Study
• ~1am: access to move LHRS to 22deg
• Run on 3H, 3He, 1H, 2H, and empty cell until Day Shift

Dec 15 Swing Shift

• See WhiteBoard
• Boiling Study: [2]

Dec 15 Day Shift

• Remove Sieve from LHRS
• Run Dummy with nominal raster at I = 22.5, 15, 10, 5, 2.5 uA -- 2 million events each (~15 minutes @ 2kHz)
• FADC threshold check
• Run Multifoil with nominal raster at I = 22.5, 15, 10, 5, 2.5 uA -- 1 million events each (~15 minutes @ 2kHz)
• Access begins at 1pm https://logbooks.jlab.org/entry/3505097
• When gas cell running is approved:
  • call RC
  • begin target boiling study [3]
