bulk GaAs wafer puck31 still has enough QE

If the gun is happy at 200 kV, without field emission, we should be in good shape, there's still QE on the wafer. First fig shows today's QE scan, second fig shows last week's scan before krypton processing (the wafer was happy sitting in the prep chamber, it's not significant that today's numbers are higher than last week's).

IN a couple hours we will know if run3 starts today (hold me Smithers)

puck swap complete, no problems

I removed puck #8, designated dummy photocathode for HV processing. I installed puck 31 which I verified to still have QE, about 1/3 the value from activation. Which should be enough for run3

Puck #31 i.d. seems smaller than puck #8, which could explain why puck 31 is so uncooperative. ANd indeed the schneedle seems to be made of aluminum, which I think is too soft and prone to generating particulates, which are bad for high voltage.
