WP11928 Install New LIGO-DAC in h1susex
Richard, Marc, Fil, Erik, EJ, Dave:
A new LIGO 28bit DAC card was installed in h1susex. The current 18 and 20 bit DAC drives can be tee'ed to the new DAC via a selection matrix. The first 8 DAC channels are being read back by an ADC in h1iscex, by the h1pemex model.
h1susex was moved from the production RCG 5.1.4 boot server (h1vmboot1) to the new RCG 5.3.0 boot server (h1vmboot0).
h1susauxex was powered down during this install.
The h1iopsusex model was modified to add the new DAC. h1susetmx was modified to drive the new DAC with any combination of the four production DACs it is driving (two are 18bit, two are 20bit).
A DAQ restart was required. Due to a DAQ configuration issue the 0-leg was offline for about an hour.
WP11937 New Cal models
Louis, Joe, Dave:
New h1cal[cs, ex, ey] were installed. A DAQ restart was needed.
WP11944 New Seiproc model
Jim, Dave:
A new h1seiproc model was installed. A DAQ restart was required.
DAQ Restart
Jonathan, Erik, Dave:
As mentioned above this was a messy restart because the new boot server rewrote the DAQ master file to only include the h1susex system. Our brief h1pemmx test yesterday did not pick this up since we did not do a DAQ restart.
The issue was found on the 0-leg, so did not impact the control room while we identified the problem as resolved it. The 1-leg restart went ahead with no issues.
After the DAQ was back up and running, we noticed that FW0 frame write times were sometimes 10-20 seconds longer than FW1's, and sometimes about the same. This situation persisted for about an hour and then resolved itself.
3IFO Dewpoint Sensor for HAM3
Bubba, Fil, Dave:
Fil investigated the HAM3 3IFO dewpoint sensor. It looks like a failed sensor.
Roof Camera
Fil, Marc, Dave:
Fil and Marc went onto the roof and restored the camera which attaches to the viewing platform. This camera is now working again.
h1sush2a DAC high quarter error
Erik, EJ, Dave:
We discovered that all the h1sush2a DACs had been in high-quarter-fifo error since 9th April 2024 (last day of O4 break). This frontend controls MC1, MC3, PRM, PR3.
We restarted the models and the DACs are now good.
See Erik's alog for details.
