swing shift summary

Shift crew:
------------

SL - Xiaochao Zheng TO - Kai Pan 3rd - John Watson

Events:
-----

17:00 - beam gets back, and start beam recovery
20:30 - NMR 59.1%
21:20~21:35 - BigBite Sieve was moved to the OUT position
22:10 - start Happex run 31503.
Run 3405 and Run 3406 are ref cell D2 target.
Run 3409 is ref cell N2 target.

Runs:
-------

3396/22268 cosmic run , junk
3397/22269 cosmic run, until beam comes back, junk
3398 2.3M/22270 2.1M, carbon run, raster off, BigBite sieve in
3399 2.3M/22271 2.1M, carbon run, raster on, BigBite sieve in
3400 1M/22272 2.1M, carbon run, BigBite sieve in

3401 is the check out run and all from 3402 to 3406 is calibration run.
The beam position before
3405 is not stable, and we also change the pre-scale twice to do the
calibration.

3405 and 3406 run are both ref cell D2 target. We stopped 3405 quickly, as
the beam position is not stable.
But 3406 is a good full run lasting 40 minutes.

22276 is a production run.

21:20~21:35, after 3406, BigBite Sieve was moved to the OUT position.

From 3407, it began the He3 production run. But the end run of 3407 is
missing due to the coda problem.

3408 1.5M/22280 1.1M

start Happex run 31503 before run LHRS#3409 and run RHRS#22281.

3409 4M/22281 1.86M

After 3409, target move to the ref cell N2 target.

3410 to 3418/- 22282 to 22289 are calibration runs, ref cell N2 target.
