CDS Maintenance Summary: Tuesday 5th May 2026

WP13221 Add BBSS Fast Channels to DAQ

Tom, Oli, Erik, Dave:

18 BBSS_OSEMINF (SUM, X, Y) DQ channels were added to the DAQ, all at 256Hz. DAQ retstart was required.

WP13223 Add PT100A VACSTAT slow channels to DAQ

Dave:

A new H1EPICS_VACSTAT.ini was generated adding PT100A. An EDC+DAQ restart was required.

WP13228 Add FW2 slow channels to DAQ

Erik, Jonathan, Dave:

Puppet was changed to add three channels unique to FW2 (STATE_0, STATE_1, NUM_WRITERS). An EDC+DAQ restart was required.

WP13235 h1sush6 IO Chassis Install

Fil, Dave:

Fil moved the IO Chassis for h1sush6 from its temporary location in an adjacent rack into the SUSH6 rack on the MER. h1sush6 front end was powered down for the duration of this work.

DAQ Restart

Erik, Jonathan, Dave:

The DAQ and EDC were restarted.

FW2 stopped at the time puppet was upgraded due to a file creation race condition.

For the DAQ restart itself, the main issue was two spontaneous restarts of FW1, both after running for 10 minutes but not synced to the writing of the second trend frame files.
