[Dsg-rich] RICH electronics and cooling system timeline

[Amrit Yegneswaran]

hi george, 
discussions with dario and sandro, and the e-mail from valery clearly indicates that the rich group needs to have the gas system ready by 1st of may 2017.

Hello Tyler, 
We will start the test of electronics boards this week. We moved the boxes from your room to F252. 
First of all we will check all 25K channels with generator and later on with PMTs at our laser stand. It 
will take at least one month to finish this job. We plan to assemble the electronics panel in parallel with 
the laser test so. 

I think that we have to finish gas system approval by May when the electronics panel will be completely assembled with 
front-end electrons and PMTs. As for my knowledge Dave Meekins gave his recommendation how to improve gas system design. 
Did we do what he requested? 

Regards, 
Valery

Hello Valery, 

This morning we received the RICH electronic boards. The boxes are in EEL 121 small cleanroom's gowning area. What would be the timeline for testing and installing the electronics?\ 

Also, when would the air cooling system be needed? A rough date is needed to give Dave Meekins, RICH gas system Design Authority, adequate time to approve the gas system since it is a pressure system. We cannot operate the air cooling system without DA approval. 

Please let us know. 

Best regards, 
Tyler
