COMMENT ON Set up optically transparent VWien+HWien flipping
https://logbooks.jlab.org/entry/4544197
Setup went without surprises, giving 65 uA to 1D in both flip states with 0.2 uA on MS and < 0.02 uA on A2. Documented viewer images for later comparison; they visually look similar.
Ready for MOLLER beam study.
BSList #121107: VWien+HWien combo spin flipper
Starting with allsave #27614 but loading lens settings from #27535.
First, turning Wiens off to establish a reference again.
Manual centering in MFG1I04A/B with MBH1I03 and MBH1I04.
Adjusted A laser phase up by 1 degree for PB zero-crossing.
Centering in A1 with MBH0I01: H: -24...-50, center at -37. V: -5...+19, center at +7.
Retracting A1, then roughly centering in A2 with MHD0I01A: H: -8.5 ... -16.8, center at -12.6. V: 5.2 ... 13.8, center at 9.5.
Sent 10 uA CW to 1D, no loss on A2. Centered on MS with MBH0I03H/V, 0.02 uA loss there.

COMMENT ON Routine Maintenance of ODH Systems (Managed by SSG).
The ESR2 ODH system is showing a reduction in flow rate. We investigated and need to replace the intake filters on the system. Talked to Sasa and we will perform the filter change at lunchtime today. Will notify Crew chief when starting and completing the task.
