Corrected 9S Vertical position drift to reduce 7S BLM activity

1 day 9 hours ago
Log Number: 4541702Logbook(s): Entry Makers: alexsBody: 

When attempting to bring Hall C back up to 70 uA from 50, we started getting a rash of 7S01 BLM trips. Path length and gang phase checked out okay. Thankfully, a good ZeroPos of the machine was in, and the issue was quickly traced to vertical position drift in 9S. A small adjustment with the 8R10V corrector brought the rels back to 0, and BLM trips ceased.

Settings Alarm Handler Limits for Injector Ion Pumps

1 day 10 hours ago
Log Number: 4541642Logbook(s): Entry Makers: suleimanBody: 

From Leo: For ion pumps with the "smart" interlocks that have delayed and fast trip, I suggest using the slow delay as a "red" alarm, as vacuum in this range will trigger a valve closure if it does not improve, then set the "yellow" alarm one decade lower as a caution warning.

1. For these ion pumps: VIP2I00, VIP1I01, VIP1I02, VIP1I03, VIP1I04, VIP1I05, VIP1I06, VIP0I00, VIP0I01, and VIP0I01A - See Figures 1-4. Then the limits are:
VIPxxxx.HIHI = 5e-06
VIPxxxx.HIGH = 5e-07
VIPxxxxV.HIHI =  6000
VIPxxxxV.HIGH =  5500
VIPxxxxV.LOW =  3000
VIPxxxxV.LOLO =  2500
