Current Daily Run Plans

The current day is indicated by a color.

Day, Date	Shift	Tasks (Responsible Party)	Comments/Status
Wednesday, December 4	Owl	No shift
	Day	Magnet work...
	Swing	Magnet work...until Jack ready to leave 4-8pm. Then 5pass tuning into A.
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
	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	th coupling, a lack of the "bow-tie" FP theta v. phi shape, and anomalous structures in the dispersive-x FD distributions
	Swing	redo dp optics scan; check minimization chase, y-target reconstruction	Q^2 measurement; quartz rate study; go to high current checkout; When should we do beam modulation and phase advance study?
Monday, December 9	Owl	Take access for removing sieves; Frame finding and centering for C-1%, Ca-40, and Ca-48; verify quartz alignment; do Q^2 measurements (C1%, Ca-40, Ca-48); quartz rate study for C1%, Ca-40, and Ca-48; Expect very similar rates for all three targets: ~150 - 200k Hz per uA	Experts coming in: Bob, Chandan, and Devi
	Day	high-current commissioning: Compton chicane tuning and ion chamber calibration, setup 150uA to dump; execute Silviu's slow thermal burn-in procedure for Ca-40 (and then Ca-48); beamline instrumentation calibration; go to pre-production width study
	Swing	pre-production
Tuesday, December 10	Owl	pre-production
	Day	Spin dance?	Spin dance if Hall C ready
	Swing	production
Wednesday, December 11	Owl	production
	Day	production
	Swing	production
