At start of shift, waiting for beam (plus ça change...)
We are at start of kinematics 5.17.
16:30 MCC sends tune beam into the hall; looks good, ask
for 1 µA so that we can run spot++ and check raster.
16:36 Spot looks good, ask for 4 µA.
17:23 MCC is working on the Fast Feedback system;
move to empty target position for caution's sake.
17:52 Fast Feedback work is completed, and they
believe that it will now be working. Move back to
18:00 Sirish suggests that we check the intrinsic
spot size. We move to empty target position in order to
do harp scans, OTR...
18:45 Harp scans and raster adjustment done; back to
19:15 Turn off lasers 4,6,7: start rotation from
0° to 270°.
19:20 Turn on Laser 1
19:21 Turn on Laser 2
19:22 Turn on Laser 3
19:48 Take away beam to go to new kinematics. Turn off
lasers 1,2,3 and start rotation to 0°.
19:55 Rotated. Turn on Laser 4
19:56       Turn on Laser 6
19:57       Turn on Laser 7
waiting for temperature to stabilize...
20:07 NMR measurement. Result = 41.63%
20:13 EPR measurement (by Vince). Result = 40.6%
We are now at start of kinematics
20:15 Move to empty reference cell. 10 minute run.
20:38 Fill Reference cell with 140 psig N2. 10 minute run.
20:56 Move to 3He cell.
While it is moving, vent and evacuate Reference cell.
21:03 Cell now in position. Ask for
3 µA beam.
22:52 ask for beam off. Turn off Lasers 4,6,7,
and start rotation of holding field to 270°.
22:55 Field Rotated. Turn on Laser 1
22:56 Turn on Laser 2
22:57 Turn on Laser 3; ask for beam back.
23:30 Take beam away; Turn off transverse lasers
and move to reference cell position. Rotate holding field back to
23:40 Turn on Laser 4
23:41 Turn on Laser 6
23:34 Turn on Laser 7
holding field: 0 °
target HWP: out
lasers: longitudinal: 4,6,7 ON
Target: empty Reference cell
Beam: 10.0 µA
