2L17-2L21 Detuning. Likely Exit Stair 4 Dehumidifier Again?

1 day 3 hours ago
Log Number: 4474999Logbook(s): Entry Makers: samariBody: 

Since the 5th there has been excess detuning in the same south linac zones where we saw the exit stair 4 dehumifier's influence in last year with the exact same time signature as the detuning likely caused by exit stair 1's dehumidifier noted late February (see linked logs). We see the same time signature on the panel feeding the dehumidifier in both north and south verified to be operation of the dehumidifiers. Would it be possible to take a look and possibly turn the dehumidifiers in both locations off to verify that they are indeed causing the issue?

Hall C OM04 conflicting readings

1 day 5 hours ago
Log Number: 4474982Logbook(s): Entry Makers: deirBody: 

We did not get an alarm for this ODH head in the control room, but an operator noticed that this head was showing <19.5% on the OTF screen.

I went out to the ODH rack in the counting house and took a look at module for Hall C. It's indicating that Sensor 4 is reading 20.2%, Figure 1.

Figs 2,3: EPICS, on the other hand, is showing this sensor at about 19.4%. It is currently in Major Alarm in the Hall C node, but that node is disabled at the moment.

At the module, all of the non-bypassed ODH heads in Hall C are reading >20%.

Looks like it may be reading this low due to changes in barometric pressure.

Bypassed OM4 ODH Head in CMTF

1 day 7 hours ago
Log Number: 4474981Logbook(s): Entry Makers: deirBody: 

Guards notified us that they saw and heard an ODH alarm in the middle of the high bay area in B58. We went to check it out under ODH2 conditions. No visible signs of a cryogen leak in the area.

Found the panel in the CMTF indicating that sensor 4 was in alarm. The panel's light for sensor 4 was blinking, indicating a high alarm. However, the oxygen readback on the panel for sensor 4 indicated that it was low with an O2 level of 19.6%.

OM5 was still in operation, so we bypassed OM4 and the alarm cleared.
