CDS Maintenance Summary: Tuesday 27th June 2023

WP11274 Replace HAM6 camera, h1cam15

Fernando, Fil, Betsy, Patrick, Erik, Dave:

h1cam15 (HAM6) camera was replaced (see Fil's alog for details). Patrick install a new server for this camera on h1digivideo3 (was running on h1digivideo1). Erik added the new camera to the DHCP server, I added the new camera to H1EPICS_DIGVIDEO.ini. DAQ restart was required.

WP11276 Add FCES channels to FMCS EPICS

Patrick, Dave:

Patrick added the FCES FMCS channels to his EPICS IOC (see Patrick's alog for details). I added the new channels to H0EPICS_FMCS.ini. DAQ restart was required.

WP11285 CW hardware injection code, use gpstime, discontinue using tconvert

Joe B, Keith R, Mike Thomas, Erik, Dave:

Following LLO, we upgraded the psinject (CW hardware injection) code on h1hwinj1 to no longer use tconvert to get GPS time, and use gpstime instead.

For gpstime to run, the version of python3 needed to be updated from 3.4 to 3.6. Mike did this and reinstalled gpstime.

I applied Joe's changes by "svn up" to get the latest code and verifying the changes.

When we tried to run the new code it would not start. We tracked this down to an install issue, lalapps were removed by the upgrade. Mike re-installed lalapps and the new code is now running.

The first run only ran for about a minute, exiting with an awg-stream error. On the second restart awg-stream connected and the exitation is stable.

WP11278 h1lsc add filtermodules, remove two 16kHz DQ channels

Dave:

I installed the latest h1lsc model (two additional filter modules) and changed the DAQ_Channels block to no longer send the H1:LSC-POPAIR_B_RF[18,90]_I_ERR_16k_DQ channels to the frame. DAQ restart was required.

DAQ Restart

Dave:

The DAQ was restarted twice, first around 10:45 in conjuction with h1lsc model and EDC restarts to apply LSC changes and add the FCES FMCS channels.

A second restart, along with a EDC restart, around 12:46 to add the new h1cam15 channels.
