Optics run summary
01:44 Cycle Q2,Q3, change HRS momentum to 2.251
BPMA in the tools gui is not very right. Not know beam pesition yet.
Need
03:34 21781/2694 Fast Raster on, Sieve out, C12

04:20 Reboot LHRS DAQ. start 21784/2698. Raster off, Sieve out, C12.

04:30 Found that T3 rate is too low at LHRS. Trouble shoot and found that the left septum power supply was tripped off. Left arm Run# from 2682 to 2698 were affected. Will need to redo this acceptance calibration later.

04:45 Escort access to move sieve in. Left septum was reset and current was set to 734.59A.

04:50 21785/2699 started. C12, sieve in, rasters off. RHRS CODA is 100% dead time. Reboot all rocs manually then run again.

5:12 change septa current to -1% (21789/2700)

5:28 change septa current to -2% (21790/2701, 21791/2701, 21792/2702 )
RHRS coda crashed during run 21790.

5:48 change septum current to -0.5% (21793/2703)

6:04 set both septa current to 730.7A (21794/2704)

6:14 set both septa current to 725.4A (21795/2705), this is the best septa current.

6:26 keep both septa current at 725.4A, change Q1 to -1% (21796/2706)

6:48 change both Q1 to 1% without cycling Q2 and Q3 (to save time) (21797(junk), 21798/2707)

7:06 keep Q1 at +1%, turn off dipole regulation and change left HRS dipole by -0.2% and right dipole by -0.3%, (21799/2708)

7:48 Turn on regulation, set LHRS P= 2.2463 and RHRS P=2.2435 (21800/2709)

Finished preparation part of the optics, will continue to do delta scan.
