Commissioning FFB, Verify Ca target with spot++. Start Ca target burn off (Call Silviu before starting the burn off procedure). BMod commissioning (call Victoria). Production
| Ion chamber calibration is done upto 20 uA. We will use the present calibration to estimate ion chamber setpoints for 50 uA and start burn off at 50 uA (look at here https://logbooks.jlab.org/entry/3824379#comment-29514). We will ask MCC to include ion chamber data upto 50 uA while burn off at 50 uA is ongoing and estimate setpoints at 100 uA.

0. Start by ramping(cycling) quads and septum back up to nominal values and take hall back to Beam Permit.
 +
1. Usual checks. Beam spot size (previously around 300 um) and raster size with Spot++ on C-hole.
 +
2. Check Compton rates at 10 muA on C-1%. If we are 20% lower in current, the Compton rates should reflect this. Let MCC know that conditions are degrading if this is not the case. Make sure HVs are correct- main detector and SAMs on and others off.
 +
3. Establish beam current at new level on Ca48 and reset IC levels. You will have to provide MCC with new IC threshold values for the current being sent. These are on a printout close to the center computer console. Verify that the thresholds are close (~7% above mean values). Check dpp and beam position are good.
 +
4. When beam is stable, call Ye (swing) or Victoria (owl) and they will check that it is safe to turn on BMOD and that the setup works. Due to possible changes in the optics tune DO NOT turn on BMod until the experts say it is safe.
 +
5. At some point the Owl crew should take new pedestal runs for new current settings: BCMs (most critical), BPMs, detectors
 +
6. Ensure the lower current more than makes up for lost Coulombs by increased efficiency.

Global Run Plan

Current Daily Run Plans

The current day is indicated by a color.

Day, Date Shift Tasks (Responsible Party) Comments/Status
Sat Aug 8 Owl waiting for beam..
Day Waiting for beam
Swing Harp scans on 4A and 4B, estimate size at target. If size at target is greater than 100um x100 um, then good to go. Otherwise ask MCC to tune. insert warm C-hole tgt, Request position locks (BPM 4A and 4B) from the white board. Take spot run, analyse and see the C-hole on spectra. Move beam to get C-hole properly. With the proper target center, determine raster currents for 2mmx2mm and 4mmx4mm raster size. When C-hole center and raster current are found, call RC for starting Optics data taking. checked beam spot size from Harp scan - 143um(x)x209um(y). Good enough for our requirement.
Sun Aug 9 Owl
Day Optics commissioning - https://docs.google.com/spreadsheets/d/1SngpqgLLULtcuKD0t9k-A2Cpmxy1jb5bIYnnP8f8zPM/edit#gid=1910123414
Swing Continue optics data taking. We are planning to skip +1 dp scan completely. After completing -1%dp scan, we will go to the nominal magnet settings and take watercell data for very high statistics (~10M) for (-0.3,-1.5) BPM A and E positions. After that we will request for an access to take out sieve. Then we will take sieve out C target (with and without raster -1M events) and watercell data 10M events for the above BPM positions. Then we will do detector alignment with VDC and GEMs. Finally Qsq measurements. If we are left with time after completing all above steps, then we may go to +1%dp scan or bulleye scan based on how much time available before MCC pushes for higher current.
Mon Aug 10 Owl Continue plan from yesterday's swing
Day During escorted access, take out sieve slits, move upstream and AT detectors to integrating mode. We are going to start high current beam commissioning after the access. With out Sieve slits data, alignment and Qsq will be done in Future.
Swing Going straight tonight (not through chicane) . Continue High current commissioning -Ion chamber calibration upto 20 uA (compare with Feb calibration data). Commissioning FFB, Verify Ca target with spot++. Start Ca target burn off (Call Silviu before starting the burn off procedure). BMod commissioning (call Victoria). Production Ion chamber calibrations done. FFB is commissioned, Burn off is done.
Tue Aug 11 Owl BMod commissioning. Detector alignment with downstream detectors (call Devi, turn on Downstream main det with -1900V. Turn off downstream quartz, VDCs and scintillators before going to high current). Production with whatever acceptable current for Compton background.
Day Accelerator is down for maintenance work
Swing Harp scan on 4A and 4B, estimate beam size at target (>100umx100um). Take spot run with C-hole target with (-0.3,-1.5) position locks and 4x4 raster. verify position locks. Moved Ca target (2x2 raster), Do alignment check (Call Devi). Hand over to MCC to address Compton background issue with 150 uA beam. FFB diagnosis and production
Wed Aug 12 Owl Continued plan from swing shift Beam back around 3 am. Adjusted gang phase, established FFB. Better Compton background rates. Detector alignment. production.
Day Started tuning through Compton chicane. If everything goes well we will go for Compton commissioning (contact Juan Carlos/Adam).
Swing Storm delayed commissioning into the evening. Got decent Compton background rates at ~11pm.
