Current Status
- Smooth running since Wednesday swing shift - completed data taking with target ladder I.
- Beam is off and hall is in the restricted access for the target ladder change work.
- Target work is anticipated to be done around Wednesday swing shift
Run Plan
- HMS EMC effect data taking at 20 deg and SHMS SRC data taking at 8 deg with target ladder II.
Resolved Issues
- Beamline vacuum - https://logbooks.jlab.org/entry/4089716 https://logbooks.jlab.org/entry/4089883
- Unexpected drop to restricted access on Saturday morning. Took 4 hrs to come back to beam permit. https://logbooks.jlab.org/entry/4091594
- Random type of failure - trying to resolve it with the manufacturer.
- 2L02 vacuum issues - https://logbooks.jlab.org/entry/4091621
Issues
- None if you could believe that. (Nevermind)
- HMS shield temperature unknown - https://logbooks.jlab.org/entry/4092473
- Runs not copied to MSS in 2+ days - https://logbooks.jlab.org/entry/4092462
Notes
- SHMS rotation to 8 deg: Rotating SHMS below 8 deg will trip the limit switch. Start with putting 8.1 or 8.2 deg on the rotation GUI to see the angle offset first then correct for it.
- HMS rotation to 20 deg: There is an increased chance that the rotation will get "stuck" and require expert intervention.
- When rotating to 20 degrees from smaller HMS angle, it is ok to go directly to 20 degrees.
- When rotating to 20 degrees from larger angle, first rotate to 19 degrees, and then to 20 degrees.
To do
Take more data!
