CDS Maintenance Summary: Tuesday 25th February 2025

WP12343 opslogin0 upgrade

Erik, Jonathan:

Opslogin0 OS was upgraded from deb11 to deb12. Its nomachine server version was upgraded to 8.16.1 (which enabled the OS upgrade).

WP12284 CP1 stop fill on temperature drop

Janos, Dave:

A new version of cp_overfill_ioc.py was ran today which stopped the fill when the thermocouples recorded a drop in temperature of greater than 60C in 30S. The new IOC has additional channels, which were added to H1EPICS_CP1.ini. A EDC+DAQ restart was required.

WP12352 Update DAQ to recent camera move

Patrick, Jonathan, Dave:

Last week cameras 11-14 (MC1, MC3, PRM, PR3) were moved from hdigivideo1 (old server code) to h1digivideo4 (new server code). This new code has a lot more EPICS channels per camera, and two channels have been removed (_XY, _AUTO). So the the past week these cameras have been missing some of their channels in the DAQ, and I had to run a dummy IOC on opslogin0 to "green up" the EDC for the missing XY,AUTO channels.

Today a new H1EPICS_DIGVIDEO.ini was created to bring the EDC up to date. A EDC+DAQ restart was required.

WP12347 Add new VACSTAT channels to DAQ

Dave:

Following the addition of the X6,Y6 gauges to vacstat yesterday, these were added the H1EPICS_VACSTAT.ini for inclusion to the DAQ. A EDC+DAQ restart was required.

DAQ Restart

Jonathan, Dave:

The DAQ was restarted for new EDC ini files (H1EPICS_[CP1, DIGVIDEO, VACSTAT, CDSMON].ini

The new EDC restart procedure was followed. The only issue was a sponteneous restart of FW1 as it was writing its first full frame.

Procedure:

• backup old H1EDC.ini, generate H1EDC.ini
• check for channels duplicates (there were none)
• for each new channel, check it exists using caget (they all do)
• when idle, stop TW0 and TW1
• restart h1edc (the rts-edc_h1edc.service on h1susauxb123). At this point the only disconnected channels are TW[0,1] (they were)
• restart the DAQ 0-leg, this starts TW0. Wait for FW0 to write frames. EDC is only disconnected from TW1 at this point (it was)
• restart the DAQ 1-leg, this start TW1
