Day, Date Shift Tasks (Responsible Party) Status
Friday, June 14 Owl
Day
Swing
Monday, June 17 Owl
Day Last day for planned collaboration work in Hall. Expecting 2A alignment
Swing Vacuum connections between US pipe and target and between target and collimator box.
Tuesday, June 18 Owl
Day Pump down the entire pivot to dump region; Expecting 2B alignment
Swing Target software checks
Wednesday, June 19 Owl
Day Hall Closed. Final Checklist. Possible first beam in Hall A
Swing Continue beam in Hall A for tuning. Start low beam checkout.
Thursday, June 20 Owl Continue low beam current checkout. Completed Collimator search.
Day Tuning
Swing Tune up and Low current commissioning.
Friday, June 21 Owl Low current commissioning. Started optics Commissioned 45deg and 90deg targets. Calibrated ion chambers. Bullseye scan.
Day High current + Compton rate tuning.
Swing High current calibration after tuning (Caryn). Low current commissioning. Restart Optics (Seamus, Sanghwa, Ryan) Basic run quality plot macro needed (Sanghwa).
Saturday, June 22 Owl Opportunistic: Beam Modulation (Paul K, Vectoria) ESR 15K helium issue, scattering chamber vacuum degration investigation
Day Optics.
Swing Low current cavity (Ye, Cip). Minimum chase.
Sunday, June 23 Owl Inner edge search (Bob, Chandan, Kent). Q2 measurement with Pb target (Bob?). Opportunistic: Beam Modulation (Paul K, Vectoria) Inner edge search DONE.
Day Minimize width.
Swing Minimize width. Minimum chase.
Monday, June 24 Owl Quartz align; quartz rate. (Dustin)
Day Optics verification. ESR 15K helium repair is ongoing.
Swing No beam.
Tuesday, June 25 Owl No beam. shift cancelled.
Day Target cooling down. shift cancelled
Swing Optics. Vacuum issue. No beam for the whole shift.
Wednesday, June 26 Owl Optics.
Day Optics. Send beam through Compton chicane. Optics complete. Vacuum valve VBV1P03 (compton table) can't be opened.
Swing Low current cavity lock test. Optics. Q^2 measurement (Bob or Kent). Opportunistic: SAM test. Cavity lock commissioning completed
Thursday, June 27 Owl Optics (db scan), Q2 measurement, detector alignment db scan, Q2 data taking completed in the morning, detector adjustment needs hall access in the afteroon
Day Send beam through Compton chicane, Compton commissioning. Fail to send beam through compton chicane
Swing Rate scan (Dustin) and SAM shutter test, raster size verification All completed
Friday, June 28 Owl Controlled access (SAM shutter removed, detectors to integrating mode), high current test (no FFB ;-()
Day Mostly down due to vacuum problem, shift BMW test with tune beam, Compton commissioning
Swing Compton commissioning, current + PITA scan, finish up high current test, BMW Unable to finish any of the task in the list, beam restoration procedure performed throughout the swing shift. Harp scan (similar spot size compared to yesterday, x ~100um, y ~ 550um). Established raster size, FFB.
Saturday, June 29 Owl Production (natural Pb, Carbon) Down due to target vacuum problem
Day Production with 208Pb? Rate studies, Phase 1. Down due to target vacuum problem
Swing Sweep + access. Phase 2 rate studies Down due to target vacuum problem
Sunday, June 30 Owl 208Pb Production. Target Fleet Commissioning Down due to target vacuum problem
Day Moller commissioning. Down due to target vacuum problem
Swing Optics - Y target finding, Bandwidth. Collimator heating axis study. Down due to target vacuum problem
Monday, July 1 Owl Down due to target vacuum problem
Day Beam Studies Target vacuum leak source found, recovery in progress
Swing Site power loss while ramping up HRS magnets after target cool down
Tuesday, July 2 Owl Down due to the site power loss, https://logbooks.jlab.org/entry/3697845
Day Down due to the site power loss
Swing Down due to the site power loss
Wednesday, July 3 Owl Down due to the site power loss
Day Still down from the power loss, CHL started CT recovery and perhaps 2K pumpdown in the afternoon
Currently we are:
Sieve OUT
Integrating mode detector
Raster off (tested ok yesterday)
Cavity in low current mode
Swing
Thursday, July 4 Owl Restricted
Day Restricted
Swing Restricted
Friday, July 5 Owl Restricted
Day Target cool down, Magnet ramp up Restricted->Controlled access
Swing Cold target monitoring, Magnet ramp up Hall to Power permit upon completion of Compton work, 5-8pm Cryo ready in SL, 8-12pm phase the SL
Saturday, July 6 Owl Cold target monitoring. Power outage in SL, no beam
Day Got 70uA to dump, then Cold target monitoring. 8am - 5S optics, tune B after 5S
Swing Cold target monitoring. Tuned accelerator, took beam away, 5S optics, tune B after 5S
Sunday, July 7 Owl Cold target monitoring. Tuned accelerator, took beam away, 5S optics, tune B after 5S
Day low current cav commissioning (for EPICS) and beamline optics Tuned C, then tune beam to A, then 20nA CW, then back taken for retuning
Swing High current Pb, Carbon 1%, BMW, current scan, PITA/IA scan Detailed plan tuning for most of shift, hope for Production CW
