Shift Summary:
------------------------------------------------------------
1. Beam was cogged at 0:20am with 9.7E9 in Blue and 8.8e9
in Yellow and the rate of the trigger 1 was around 30.
This beam last until 8:00am and the trigger rate
decreaseed to about 5.
2. Run 2273 MRS at 90 deg. 4K Gauss 13K collisions
Run 2276 50K collisions
(Total no. of collisions for MRS at 90deg. 4K Gauss is
about 200K collisions in run 2238,2248,2254,2256,2258,
2269,2270, 2273 and 2276. Note that between run2258
and 2269, MTCP1 voltage was changed from -1250 to -1130V).
MRS field changed to 2K Gauss (350A).
Run 2278 MRS at 90deg 2K Gauss 50K collisions
Run 2280 22K collisions
Run 2283 15K collisions
Run 2285 7K Collisions
Run 2286 MRS at 90deg. No field 10K
3. Each above run was terminated by evb Error status (
camac-evb Errors for the first two and fb3-evb Error for
the rest) except the last run. In order to begin a new
run, one or two runs had to be abundaned, by click Clear
Error and Begin Run until it starts. This is why the run
numbers are jumping. It sems to ocuur more frequently by
time.
