URGENT: Shifts in January/February need help - only 4 openings remaining

Next opening: This Saturday Sunday OWL

Thursday DAY - Friday DAY : SL's on standby (likely cancel SL shifts, keep TO shifts as target is cold)

Accelerator and Hall Status

• Beam Permit SBS - 14
• Tomorrow: Restricted access - configuration change to SBS - 8 , sieve slit in request

Run Plan

• Continue SBS -14 data taking until 7am Thursday.
  • 5 LD2 10 uA 100M (~5 hours) In Progress (51M events @ 9:30 am)
  • 6 LH2 15 uA 20M (~2.5 hours) Wednesday DAY
  • 6 LD2 10 uA 100M (~5 hours) Wednesday SWING
  • 6 Dummy 20 uA 10 M (~1.75 hour) Wednesday SWING
  • 7 LH2 15 uA 20M (~2.5 hours) Thursday OWL
  • 7 LD2 10 uA 100M (~5 hours) Thursday OWL Beam off before 7am. Rampdown SBS, BB, turn off HVs.
• Thursday
  • Beam off 7am Thursday 1/20
  • Ramp down SBS, BB, power off HV's (the procedure for transition to controlled access on the wiki doesn't mention any HV..?)
  • Sweep 8am-8:30am
  • Restricted access
  • Change configuration to SBS - 8
• ...Friday....
  • close hall - beam permit
  • Cosmics with SBS on (70%)...
  • new HV setttings for new calorimeter...
  • Beam checkout Fri SWING: Harps, carbon hole, SBS ramping procedure, IC calibration
  • Sieve slit in optics data - SBS off 1foil GEM alignment. SBS on multi foil (5) optics.
• Sat OWL
  • possible issue with escorted access to remove Sieve slit (radcon support?). Push to SAT DAY?
  • Sieve slit out - ARM/escorted access of expert to remove slit...(2-3 ppl (1 shifter?) including 1 expert needed to remove slit)
  • Sieve slit out data...
• OPS downs?
  • Accelerator needs to understand what performance that they can get from SL18 cavity to plan for the next run periods beam energy.They are proposing a 3-4 shift beam down
  • (option A)Jan 25th day and restoring beam end of day Jan 26th
  • (option B)During kinematics change on Monday Jan 31 and Tues. During down time 1/31-2/1
  • (option C)From 1/20 day when we will move BB/SBS
  • B goes to 2 pass Monday DAY 1/25

Today's Run Plan

SBS-14 Long term plan

Unresolved Issues

• SBS Magnet Spikes. Requires access hereJack's Entry
• Ben Raydo needs opportunistic access for VETROC/GRINCH

Subsystem Updates

Beamline:

analysis of BCM data progressing and expect results on BCM calibration near the end of the week

DAQ general

HCal

replay issues corrected

BBCal

50k replay done

Timing Hodoscope

GRINCH

single event display working. Will go into hall - missing channels in vtrack. hits seen in vtrack corresp to det geometry. cleanup randoms and got plot picking out 6 tubes firing on average

GEMS

Replay analysis

Bob Michaels supplied getcharge script to beam beam charge from scalars, gives same result as normalizing to # of triggers
