010 valve at 1L02A changed out, CM 1L02 valved in and
ready to pump when windows are done. pressure bypass
closed. Data logging on. We found the bellow was originally
incorrectly installed with the rotatable flange on the wrong side,
requiring a second changeout.

ScanNPlot has only been built for rhel7 machines.
I've added "rhel7 only" to the jmenu entry.

Tried opening the newly released ScanNPlot at UITF on machine itfl03 and recieve the error shown below. This is a RHEL 6 machine. Works fine on RHEL 7.

Booster has been off for a while so I optimized phase offset to hopefully help in cavity stability.

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)

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.
