Production Run List
Start Slug 12, IHWP In, FFB on always
- Good - run3595
- Good - run3596
- Bad - run3598
- rcdb says current scan but BCM yields are ~70uA, RMS on detectors look OK!
- 128 ppm charge asymmetry in BCMs, no Aq running ? -> There are 3 periods of different avg Aq, so maybe a cut will cut out the very large bad Aq stuff
- BPM 4ac still saturating and 4eX still 12 um widths
- Bad - run3601
- Mini-run 0 has ~4X RMS (det reg_asym). Note: Aq feedback off, RHWP rotated back to nominal value
- There is large BPM noise (20 um widths in the online plots, though it may be some strange outliers)
- Good - run3602
- Good - run3603
- Good - run3604
- Good - run3605
- Good - run3606
- Good - run3607
- Good - run3608
- Not sure why the run was too short
- Too big Aq
Non-Production Runs and Bad Runs
- Junk run3589
- Junk run3590
- Junk run3591
- Test 50uA run3592
- Test 50uA run3593
- Test run @50uA large Aq mean
- Junk run3609
Pedestal/Calibrations Updates
- DET HV Calibration run3594
- Calibration - run3597
- RMS (after regression) is fluctuating between miniruns. Looks like current scan run!
- It is a current scan, bad Aq
- The BPM4ac is saturating the whole time
- The BPM 4eX is very wide (12 um widths)
- PITA Scan RHWP=500 run3599
- PITA Scan RHWP=500 run3600
- Aq feedback is off, very short run with elevated det width, big Aq mean
Issues
- Starting from the beginning of production running analysis fails all events without any indication why HALOG
- Analog BCMs are too noisey for recent runs HALOG
- Regression seems to be failing for run3604 run3605HALOG
- Double peaks and shoulders in bcm dd run3604 run3605 run3603 HALOG
- Residual correlation with AqDs3 run3605 run3604 run3603 run3602 run3601
- Seems all the runs have fluctuation on RMS on combined asymmetry (postpan).
Other Status Updates
- Accumulated charge = 12.65C
- Changed regression set (and added combined BPM 4a_4ec X) - git commit - HALOG
- new file: prex_combiner.3583-.map
- new file: prex_corrolator.3583-.conf
- Updated postpan regression "combo_reg.3583-.conf" - git commit 3f8fa67 (prompt repo commit aea4bb3), HALOG
- Added aggregator scripts to prompt repo - commit 6838abbbae9ca3e02a3a2d6e8d29050b5f9d2437
- Updated priliminary pedestal maps for 70uA running (for Main, AT, and SAM detectors) HALOG
