Production Run List
- Slug 27, Wein_Left, IHWP_IN
- continued from 2August (runs 3811-3813)
- runs 3814-3821
- temperature increases in collimator lead to a lowering of beam current by shift crew
- beam current consistently lowered throughout the slug to find temperature stability
- main detector widths increased throughout the slug as well
- target changed from D9-208Pb-D10 (this target experienced ~20C over its lifetime, ~15 good)
- good production running
- runs 3822
- new target D7-208Pb-D8
- good production running
- collimator temperatures low and stable
- run 3823
- good production running
- increased raster size
- Slug 28, Wein_Left, IHWP_OUT
- runs 3824-3838,3840 : good production running : ended on 4 Aug.
- run 3839: suspicious, large MD width
Non-Production Runs and Bad Runs
Pedestal/Calibrations Updates
Issues
- increased widths as target D9-208Pb-D10 degraded (through run 3821); improved with new target (run 3822)
