So Far

  • Taking production data, Tungsten 2.8% @30uA.

Plan

  • Continue with production on tungsten until tomorrow ~8:30.
  • Beam energy reduction: from 2.221 GeV to 2.139 GeV (~4%):
- The change with take place tomorrow and is expected to be completed during tomorrow swing.
- HRS Kinematic setup will be accordingly changed.
  • The RF recovery was planned from 8:30 to15:00 tomorrow. This will be covered by the energy reduction setup.
  • The Hall will be in controlled access for tomorrow day shift.
- Switch the right arm polarity, from positive to negative, for the optics data.
- Roman: need access to Hall A tomorrow to reboot Moller DAQ crate (~10 min) and to check Left HRS VDC realy box (1-2 hours).
- Doug will be available to provide the Hall walk-through training tomorrow.
  • Labyrinth network switches? Now or after APEX?
