Subject: MCIS "PV" PLC trip overnight 

Another in the on-going saga of MCIS:PV1 trips occurred again this morning. The operators recovered most of the vacuum devices except for the IM section gate valves. We had an in-person discussion about them, the order in which they should be opened, and the existence of a hand valve in the IM roughing line. An ION note is needed.

Lots of other things were different, and beam was off. Restoring the tune basically restored beam. Whatever. Here are two emittance scans, one after restoration, one after further work. 18O4+ as before, but RF power arbitrary, and probably not identical to yesterday.

Ack! EL keeps tripping... Stay tuned.

Later... Jane is alpha-testing an application for our development. She is using the source presently. Development on hold.
