Chicane dipoles showing latched alarms, suspect com problem

1 day 23 hours ago
Log Number: 4468733Logbook(s): Entry Makers: eformanBody: 

Noted that the chicane dipoles are showing latched alarms, but no alarms are showing if the nodes are expanded (see fig. 1)

I opened the expert screens for the dipoles and some of the PV's are not communicating (figs. 2-5).

The dipoles are powered on and responding to current/Bdl setpoints appropriately and deflecting the beam as expected.

Centered A3 w/ CW

Log Number: 4468729Logbook(s): Entry Makers: bschaumlBody: 

Checking centering in A3 with CW as a continuation of what we were doing on day shift. The decrease in interception was fairly minimal, but it is properly centered now. Slight increase on A4, but I'll be messing with stuff further upstream soon and will need to revisit this anyways.

0L03 ODVH values

Log Number: 4468717Logbook(s): Tags: Entry Makers: beneschBody: 

0L03-4 CWWT is now good per linked entry. Running lemi with that cavity on will lower 0L04-8 too much. I suggest ODVH for cavities 5-8 be set to 6 MV/m, a reduction of 8 MV/m total, to overcompensate for the return of 0L03-4. This will bring 0L04-8 up 0.7 MV/m - still low. If its stability becomes an issue, set 0L03 cavities 5-8 to 5 MV/m.

For work at 119.6 MeV leave the ODVHs as is. For that condition it may be desirable for me to undo the 0.5 MV/m reductions in GSET.DRVH and ODVH of cavities 1-4 I made during the SAM to lower fault rate.

COMMENT ON Bench Test FDU

2 days 1 hour ago
Log Number: 4468712Logbook(s): Body: 

Troubleshooting revealed a bad Terminator AC power supply, a bad Astrodyne 24 VDC to 24 VDC, DC/DC inverter and a bad filament power supply. All but the filament power supply have been fixed. The filament power supply is obsolete and two refurbished power supplies have been ordered; one to replace the bad one and the other as a spare.
