Continue taking polarized deuterium data. The wire chamber R5 suddenly started tripping during the run # 11641 and I could not stop it until I lowered the high voltage to 3775 V. Later, a bad beam filling happened and the wire chamber hv had to be lowered even more. It is set 3750 V at this moment.
Run # 11636 11638-11645 should be all right.
Run 11637 is a junk.
However,
Run # 11636 and 11638-11640 have normal wc hv.
For run # 11641-11644, wc r5 hv is 3775 v.
For run # 11645, wc r5 hv is 3750 v.
