  • D. Meekins target work completed and cool down of LH2/LD2 will be done today late in the morning
    (there are issues with beam-line vacuum that will need to get resolved before locking Hall C for beam)
  • After work is done, S. Lassiter will need to do rotation certification before spectrometers can be rotated (before Friday afternoon)
  • J. Beaufait will do Hall C walkthrough Friday @ 2:00 pm, afterwards, Hall C will be swept and go to beam permit.

Current Issues

  • beam-line vacuum issues (too low):
    • Hall C target chamber and downstream dump-line vacuum readings are 3e-5 torr and 200 torr, respectively.
    • Meekins does have some recommendations for that system, but will not make any changes without talking to Walter Kellner first
    • Cause of vacuum leak: Vacuum Leak
