Until 1:00, finish data taking at (-90,180). Final accumulated charge at this kinematics is 10.1907 C.

1:13 Start quick test run to check E-arm VDC efficiencies at 5uA. Run# 2424.

1:16 Dto, but lower prescale factors. Run# 2425.

1:22 Setting up for pointing runs.

1:27 Pointing run w/ 10cm dummy, run# 2426

1:35 15cm dummy, run# 2427

1:41 4cm dummy, run# 2428

1:50 carbon target, run# 2429



some time while hrsh is being changed by other losers on shift:

HARP scan #943, coda run 2430



2:05 End harp scan. Setting up for new kinematics (50,180).

2:35 New kinematics set. Run 2431 is junk.

2:41 Carbon pointing run, run# 2432

2:49 4cm dummy, run# 2433

2:57 15cm dummy, run# 2434

3:07 10cm dummy, run# 2435

3:12 Moved FPP 1.5, 3, 9in carbon doors in, as per run plan

        Setting up for production running.

3:18 Run 2436 is raster check. Prescale factors are all 1 except PS5=65000.

3:20 Asking for 70uA.

3:27 Trigger efficiency test, 71.5uA, run# 2437.

3:28 Beam died for some 30 seconds during this run.

3:31 End trigger check

3:33 Start production for (50,180) kinematics, run# 2438

4:47 Opened collimators on both spectrometers. Next run# 2440

7:40 Jim Kelly calls, alerts us to a problem with the BCMs (see halog 44646)
