At start of shift doing production running at Kinematics Q2_f40r.
Running at 80 microamps, current limited by a problem with the high power heaters in the target (see halog 86398)
run 1643 in progress at start of shift.
8:50 run 1644 started
9:40 J-P declares there isn't any problem with the high power heater. Requested 100 microamps from MCC
9:50 run 1645 started
10:00 requested 110 microamps, without any heroics, got 107. We'll take it!
10:35 run 1646 started (with header corrected for Q2_f40r)
11:13 optics runs 1647, noticed beam spot was off center
Had MCC recenter beam
11:19 optics run 1648 with more centered beam
11:24 switch to kinematics Q2_f50r
Arun does his harp tests during switchover
Right arm: 58.509 degrees P0=1.6870 GeV/c
Left arm: 20.34 degrees P0=3.5829 GeV/c
11:38 Arun is finished and we're ready to go
11:48 Run 1649, optics run, started.
12:00 putting in LD2 target
12:08 Run 1650 started
12:58 Run 1651 started
13:57 Run 1652 started
14:12 ROC14 crashed, reset and restarted coda
14:16 Run 1653 started
14:29 more problems with ROC14
14:41 Run 1654
14:55 MCC says They're having problems with injector steering. Low current for 5-10 minutes. was less than 5 minutes and not very low.
14:57 More ROC14 problems
Having trouble getting CODA back up
Reset ROC's with help from Bob and Bodo. Looked like they did all the same things we did but somehow it works for them??? Suspect maybe we didn't wait long enough after resets. You must check and make sure the resets are complete before restarting CODA. Bodo likes to type "i" in the ROC control screens. You get a nice table if all is well. If you get an exception you probably want to reset again.
15:20 run 1656 started
Still running at end of shift
