Program Deputy Weekly Summary, presented 2026-08-05
- PROGRAM DEPUTY: Rylen Latosky
- DATE (from):
Since yesterday there have been reported problems with SEE BPM iocs not reading correctly and/or being found in Expert Mode. This appears to have resulted from a user inadvertently leaving some of the iocs in FastSEE mode. This prevents the normal SEE Mode positions from being reported.
To forestall possible confusion, FastSEE Light mode is fully compatible with normal operations. However, for FastSEE Light mode to function, the ioc has to have been in FastSEE mode at least once since rebooting.
The following box supplies were CYCLED by version 2-16 of the Box Supply Cycling Script:
ARC2A Ramp Rate = 6.939 A/s
ARC4A Ramp Rate = 10.989 A/s
ARC6A Ramp Rate = 9.222 A/s
ARC8A Ramp Rate = 11.962 A/s
ARCAA Ramp Rate = 12.581 A/s
RSEP8A Ramp Rate = 10.612 A/s
Beam Conditions:
Total Linac Current (R2XXITOT) = 0
Hall A Current (IBC1H04CRCUR2) = 0
Hall B Current (IPM2C24A.IENG) = 0.0932516
Hall C Current (IBC3H00CRCUR4) = 0
Hall D Current (IBCAD00CRCUR6) = 0
BSY Current (IBC4C00CRCUR5) = 0
INJ Energy (MMSINJEGAIN) = 119.615
NL Energy (MMSLIN1EGAIN) = 1060
SL Energy (MMSLIN2EGAIN) = 1060
Gradient Problems:
0L02-7 Klystron Cathode Current (KCCU)=0.00396729 (<=0.7A)
0L03-1 Local Oscillator Power (LOPW)=40.3 (<=70mW)
1L04-8 Gradient Loop Detector Error RMS (GLDER)=108 (<0 or >=80ppm)
1L05-5 Klystron Cathode Current (KCCU)=0.0067749 (<=0.7A)
1L06-1 Measu
Calls: none
CIS activities:
- Beam QE scan and spot move with on-call staff training: summary by Marcy #4537606. Submitted the draft procedure to Kathy for finalization.
- tunnel access with Facilities to plan for a new penetration in the laser room wall
Charge lifetime: can't interpret the most recent data yet as the spot move happened only yesterday. But, assuming we get a lifetime similar to before, the new spot position should last us through the run.

Task did not happen during Tuesday's MD - Manpower diverted to emergency response elsewhere.
This is a high priority task - WA LCW pump currently in operation has developed bearing / coupling noise and vibration and should be taken out of service as soon as reasonably possible.
