CDS Maintenance Summary: Tuesday 22nd July 2025

WP12691 Install production GC/CDS network switch

Jonathan, Nyath:

The production Juniper GC/CDS network switch was installed and the temporary Brocade switch removed. The control room phones were transferred one at a time to verify the switch port configuration.

WP12690 Vacuum HAM1 Ion Pump Readout

Gerardo, Patrick:

For the past few months the IP13 EPICS channels have actually been reading out IP1_B's signals, and IP7_A which has actually been reading out the new IP13 signals.

Patrick made the internal hardware mapping Beckhoff changes on h0vacmr to map IP13 with its signals.

In the new system there is no IP7, but we elected to keep these channels in place so that recent HAM1's Ion Pump data can be trended using the IP7_A chans.

Attached plot shows IP13 (blue) transistioning from IP1_B (orange) to IP7_A (green)

WP12689 Add two 512Hz fast channels for HLTS PR3,SR3

Jeff, Brian, Edgard, Oli, Dave:

This morning we started updating the h1suspr3 and h1sussr3 models but the number of DAQ changes was significantly more than the expected two additional fast channels per model so we needed to review the changes in detail. Here is what I found

In sus/common/models three files were changed (svn version numbers shown):

HLTS_MASTER_W_EST.mdl production=r31259 new=32426

SIXOSEM_T_STAGE_MASTER_W_EST.mdl  production=r31287 new=32426

ESTIMATOR_PARTS.mdl production=r31241 new=32426

HLTS_MASTER_W_EST.mdl:

only change is to the DAQ_Channels list, added two chans M1_ADD_[P,Y]_TOTAL

SIXOSEM_T_STAGE_MASTER_W_EST.mdl:

At top level, change the names of the two ESTIMATOR_HXTS_M1_ONLY blocks:

PIT -> EST_P

YAW -> EST_Y

Inside the ADD block:

Add two testpoints P_TOTAL, Y_TOTAL (referenced by HLTS mdl)

ESTIMATOR_PARTS.mdl:

Rename block EST -> FUSION

Rename filtermodule DAMP_EST -> DAMP_FUSION

Rename epicspart DAMP_SIGMON -> OUT_DRIVEMON

Rename testpoint DAMP_SIG -> OUT_DRIVE

DAQ_Channels list changed according to the above renames.

DAQ Changes:

This results in a large number of DAQ changes for SR3 and PR3. For each model:

+496 slow chans, -496 slow chans (rename of 496 channels).

+64 fast chans, -62 fast chans (add 2 chans, rename 62 chans).

Work Rescheduled:

We ran out of time this morning so the h1suspr3, h1sussr3 model restarts and DAQ restart has been rescheduled for next Tuesday, 29th July.

The ETMY Sat Amp swap this morning was completed in 15 minutes, meaning the HWWD did not complete its 20 minute count-down.

It appears that the false-positive HWWD rate for ETMY increased with the new Sat Amps, unlike ETMX where they have disappeared, or the ITMs where the rates were unchanged.

ETMY HWWD STAT and COUNTDOWN trends show below.
