Subject: MCIS development with 33S5+ 

MCIS was running with background only. Prepare to open SO2 source gas...

MCIS:IG1 = 5.4e-8 Torr

TP1 = 13W

TP2 = 10W

Status: Leak valve closed, line valve open.

Bump leak valve carefully... but not carefully enough. Pressure bump, and back to 6e-8. I am using line valve as a needle valve. Pretty touchy, but it works.

 IOSIOC whiteouts and other funny things... I will ask assistance from ICR.

MCIS:IG1:= 7.4e-8 Torr with line valve barely cracked.

Well, it turns out that ICR is having trouble with other ion gauges in apparently unrelated sections. Interesting. Meanwhile, MCIS:IG1 trippd off and EPICS will not allow a reset. MCISIOC looks white... restart it.

Later... Controls + ICR have rebooted PLC1IOC and PLC2IOC, and perhaps others. Anyway, stuff is working again. Beam is on to MCIS:FC1 and IOS:FC3.

Later... Still no beam visible on FC6. But IG1 has crept up to ~2e-7 Torr. Open cage and adjust down. It's just about the smallest increment I can make, but it's a big step down. Meanwhile, The readback for IOS:MB field went crazy for a moment. I have it on a Stripchart, below.

Later... Liftoff. We now have 200epA on FC6 at 13.10GHz. Let it sit for a bit. Other possible resonances at 13.17, 13.24, 13.27, 13.34GHz.
