Entry number 298866

Shift start with control access. RHRS magnets are ready; LHRS dipole is still down. Both VDC off. LD2 target.

16:13 RHRS Q3 is cycled. Didn't see Q2 history. So cycling it to 1400A and back.

16:31 LHRS Dipole recovered (miraclely)

16:41 Beam permit; Beam recover with Compton

17:13 Harp Scan:

• sigma u = 0.166
• sigma v = 0.19
• sigma x = 0.25

17:15 Establishing New Beam Recovery Procedure (for BPM A = B = (0 , 0)mm) by Yi Qiang

• 200K Event run to check out detector: run 4915/25363

18:00 Asked for 100uA beam for production

18:09 Experts finish the checking. Starting production run 13868/4917/25366

18:21 Beam off for some hall B tuning. Stop run.

• MCC was trying trying and trying
• MCC don't like our new beam position (0,0)mm. Told them to find any better one betwee old and new.
• MCC keep trying trying and trying

20:47 Control Access for quick fixing on PVDIS DAQ narrow trigger

21:07 Control Access ended

21:33 Beam back. Starting tuning precedure @ new beam location = BPM A = B = (-0.7,0.0)mm.

22:16 Start Production Run : 11870/25373/4925

22:13 Start Production Run : 11871/25374/4926

Production run list

1. 13868/4917/25366 <- Stopped early due to beam problem
2. 11870/25373/4925 <- Beam Trip a lot in the middle
3. 11871/25374/4926
