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

Issues

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.
  • SHMS DAQ work during the Christmas break by Bob Michaels?
