[Dsg-halla_ecal] Fw: ECAL heater controls update

[Marc Mcmullen]

Hi Don,

Both of those signals (heated volume middle and cooled volume middle) are in EPICS now.

Hi Don,



We have completed some hardware and software updates to the system and the system is available for heating.



The cooled volume pressure has been added and we have added an an extra module for the control voltages. There are a maximum of 13 control voltage channels for each module, the last one has 9 channels.



We have added some of the EPICS process variable which I believe you have requested archival. The EPICS will still need some work done on both the heated and cooled middle temperature signals. All of these can be viewed on the GUI, we just need to get the plotting and archiving going.



The top heated volume sensor, the cooled volume pressure, and the cooled volume sensor can be monitored through EPICS.



You will have the latest GUI update on the desktop which has indicators for the new pressures, and enclosure temperature signals. I'll put that on by 5:30 today.



I will update the mailing list with any progress.
