keyword=[target] pol. to zero, then recoveredTarget incident:
I guess I was distracted by the duplicate file problem.
The target polarization went to zero. This happened during
run 4427 and 41281. Those runs are probably junk.
(There was no R-HRS run since the dipole was settling).
We've recovered now (fig 1) and will run 4428 and 41282.
Also, R-HRS run 23381 since dipole is settled.
Details of incident
The nose level was too full at one point (1/2 hr ago) and
I was advised to go to zero on manual set point. But it seems
this is dangerous. Then the nose emptied and target heated to 40K.
Noticed this, turned off microwaves and turned off beam.
Put man setpt to 1.5 (max). Nose filled, target cooled, turned
on microwaves. Good thing it's a forgiving system.
Presently, as I type this, I see 30.9 %
