| Thursday, December 5 | Owl | 5pass tuning into A. | |
| Day | RF stress test to A/RF fixing | Burned up 3 raster power supplies (ended test at 4:15pm!) | |
| Swing | Go to 1 pass; Septum problem (only up to 400 A); collimator centering; polarity check | Set HRS tune P for this septum setting for polarity check--not conclusive | |
| Friday, December 6 | Owl | spectrometer setup did not allow target alignment checks | Beam gone at 3:40am due to Network issue |
| Day | Hall surveyed and in controlled access all day; remove diffusor at end? | Septum control software fix; compton e-det work; network issues run down; raster sync problem fixed | |
| Swing | lock up hall; reverse septum polarity; raster size and hole locations | Left arm NMR probe lock not working--will have to use Hall probe; couldn't put any beam on Ca-40 due to dump FSDs (and beam optics problem -- MOLLER quads set too high) | |
| Saturday, December 7 | Owl | Tried ion-chamber calibration, but failed; started spec commissioning | First pass optics DB looks good; started septum setting and inner edge searches. Right dipole tripped so need to redo inner edge search |
| Day | Jay re-establishes Yves nominal crex beam transport setup; re-check raster size (1.8 x 1.4 now is ~2 mm x 2 mm); new hole centers (did not change much); ion-chamber calibrations done for No target, C-1%, Ca-40, and Pb#4 (on cold ladder); resumed spec. commissioning | Found out reason for raster optics issues: Moller quads not set correctly after 5-pass backout causing wide and short raster settings that evolve to tall and narrow raster at the dump (but 2x2 at the target)... | |
| Swing | Re-did inner-edge septum scan, spot minimization chase (Sangwa, Ciprian) with quartz checkout (Devi); (call Bob) start optics commissioning | We established the preliminary 2mm x 2mm (+/-0.1mm) raster (1.8 x 1.4 MCC), but should be double checked/tweaked before going high current on Calcium | |
| Sunday, December 8 | Owl | Continued Optics commissioning: dp scans with water-cell measurements most of shift | Experts coming in: Bob, Chandan, and Siyu |
| Day | Authorize 150uA; finish optics commissioning; Followup optics studies performed: Q1 scans (-10 to -20%) at +5% septum, nominal tune "P", find best Q1 setting, then scan Q3's to effectively minimumize the FP y widths | The established tune "P" for crex gave large x/th coupling, a lack of the "bow-tie" FP theta v. phi shape, and anomalous structures in the dispersive-x FD distributions; seems to be some quad strength in the septum field that is cancelled out by lowering Q1 | |
| Swing | Established CREX tune: "tune P" with +5% septum, -17%/-15% LQ1/RQ1, -5% Q3s. Redo dp optics scan but without w-cell runs, y-target reconstruction | Right dipole tripped OFF at 10:15pm, started ramping back up at 3AM. Aborted sieve-in optics. | |
| Monday, December 9 | Owl | Took sieves out and proceeded with frame finding/quartz alignment and rate activities. Bob is working to fix left arm spot. R dipole back and stable by 6am, however N Lical went down at 5:30am due to vacuum issue(s) | Experts coming in: Bob, Chandan, and Devi |
| Day | SL shift cancelled; TO still required. Hall surveyed and in Controlled Access for opportunistic work | Compton work in the hall; Accelerator down at least until 8 AM next day and may restore beam delivery by 12pm tomorrow | |
| Swing | SL shift cancelled; TO still required | ||
| Tuesday, December 10 | Owl | SL shift cancelled; TO still required | |
| Day | Still investigating vacuum issues in the N. Linac. Spectrometers up and running smooth | Hall in Controlled Access for more Compton e-det and laser work; Hall is ready for beam. Caryn is coordinating a solution to the raster size and FSD lower limit issues | |
| Swing | N. Linac problem fixed; waiting for beam | Around 10pm, accel was ready but Ops-controlled valves in the A-line downstream of the wall were not remotely controlable and no remote status update. Problem was investigated, but not properly escalated and continued into Owl |
