CDS maintenance Summary

Faster front end computer install in end station SUS [WP5351]

Jim, Dave:

h1susex and h1susey front end computers were upgraded to the faster computer model. The SUS QUAD models processing time decreased from 51uS to 31uS. The TMS SUS models processing time decreased from 13uS to 10uS.

Additional ADC install in end station SUS

Richard, Dave, Jim:

An additional ADC for the PI model was installed in h1susex and h1susey IO ChassisThe IOP models h1iopsus[ex,ey] were modified accordingly.

FE slow channels added to DAQ via EDCU [WP5352]

Dave:

the H1EDCU_FE.ini file was modified to add one slow channel from each front end computer to the DAQ via channel access. The IOP models' ADC DuoTone channel was chosen as a continuously varying signal. This is being used to investigate the FE channel access freeze issue.

The two copies of the H1SLOW-H1FE EPICS gateways were stopped and one new gateway was started.
