Status
- Beam down from Friday night to Saturday later afternoon
- - Friday ~22:00: Beam down due to the cavity/vacuum (1L25-8/1L26) issue at north linac;
- - Saturday 18:00: Beam restored;
- - 18:00-19:00: escorted access for VDC Left U2 cable checking );
- - Back to production.
- Productively collecting data over after the downtime. Total charge 2.3C from Sat 19:30 to Today 6:00.
- Yesterday ~21:53: Bogdan increased the HV for Left VDC, from -3500 to -3600. Efficiency improved.
- Earlier this morning ~6:00: CODA stopped working, from run 4585. Fixed by Alex. https://logbooks.jlab.org/entry/3662865

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
