16:00 Still waiting for beam
16:45 Beam returns. Begin Moller measurement.
17:55 Problems with beam. Pulsed beam.
18:09 CW beam.
18:35 Moller finished. Asked MCC to change bpm survey offsets to:
ax=-1.899 ay=-2.627
bx=-0.848 by=-1.407
19:07 BPM survey values now set.
Run #3038 - Cosmics
Run #3039 - JUNK
HARP scans to study beam positions
Run #3040 - HARP #958 bpm x=0, y=0
Run #3041 - HARP #959 bpm x=-1, y=-1
Run #3042, 3043 - JUNK
Run #3044 - HARP #960 bpm x=-1, y=+1
HARP #961 bpm x=+1, y=+1
Run #3045 - HARP #962 bpm x=+1, y=-1, maybe not good.
19:55 Asked to go back to bpm x=0, y=0. RF trip.
21:03 Beam back.
Thcm 90 degrees pointing:
21:04 Run #3046 - carbon target, 5uA, raster off
21:12 Run #3047 - 4cm dummy
21:19 Run #3048 - 15cm dummy
21:21 More RF problems.
21:54 Run #3049 - 10cm dummy
Beginning production point thcm=90.
Including aerogel in trigger.
22:06 Run #3050 - trigger efficiency check
6msr collimator runs:
22:14 Run #3051 - 47uA.
Run ended due to 100% deadtime. End run failed. Kcoda.
22:25 Run #3052
(all runs previous to this, at this setting,
have the wrong hadron angle in start of run)
open collimator runs:
22:58 Run #3053 1.3M events
23:15 Run #3054 1.3M events
23:35 Run #3055 1.3M events
