  1. Running update: - Ciprian
    • SAMs: the problem with the SAM voltage was not found in the amplifier. Next step would be to look in the RHRS.
    • PITA scans: updated the script and ran 2 PITA scans for DVCS. They are sent to minimize charge asymmetry.
    • Cavity BPMs: we should take a look at the output from the cavity BPMs after last Wed. CP: will do. KP: we should look at them on a scope. CG: will do.
  2. Stripline BPMs (4E): - Caryn
    • KP: what was the decision for 4E? CP: DVCS is aware but seem reluctant to do anything about it. It seems to not affect them much.
    • KP: we should mention it to Thia when we get a chance.
  3. New data: - Caryn
    • CP: Run with solid target at 5uA.
    • CP: how is the pedestal analysis going? TY: already sent list of control.db files. CP: we need pedestals for the solid target runs. TY: will get on it for both the SAMs and BPMs
    • KP: we need to organize (elog) on which runs are important TY: will do
  4. PREX/CREX FOM calculation: - Tyler
    • KP: how it the FOM calculation going? TK: meeting tomorrow
