July 27th-Aug. 3rd
- Beni ramped up the solenoid on Aug. 1st. However, due to a problem with the PXI readout, it was ramped down. The solenoid was ramp-up again (Aug. 2nd) to its nominal 1350A, this time without problem.
- Target was cooled (C. Keith) and latter filled without problem (Aug. 1st)
- Shift Started on Aug. 1st, 8am.
August 1st-2nd : investigating and attempting to fix a problem with the front-end of the TagM. Did two long accesses to tagger, but the problem remains. Due to this, the runplan for August 3-4 has been reorganized
- CW beam arrived around 3am on Aug. 2nd, followed by beam quality checks.
- Radiation levels are good.
- Beam convergence is good
- Beam position optimized (?), however transmission doesn't appear to be optimal
- trigger checked out
- Radiation level study done.
- CDC HV scan ongoing.
Issues:
- TagM
- We often get less beam current than requested
- DAQ start run issue
- Difficulty in setting CDC HV for CDV HV scan, see also Keigo's entry
Upcoming days:
- Hurricane/tropical storm Isaias
- TagM communication issue
- Week 1 time chart
- Richard plan for Act. Col. test
- Thursday: 1->5 pass change for Hall B. Hall A on-line.
- Tuesday 11th: Maintenance day?
