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?
- Paul K.: update firmware for BMP4B/C/D receivers, should be no impact on APEX. https://logbooks.jlab.org/entry/3663077
