[Clas12_rich] RICH cooling, interlocks and assembly structure

[Brian Eng]

For the RICH guys/gals,

Can you send us the model of the LV & HV supplies you're using so that we can see what types of interlocks we can use for them?

Thanks

>> We have received Valery’s suggestions on the interlock system and as in my previous email, please let us know of any other interlocks would be required. For the hardware interlocks, we will develop a cRIO-based system identical to the SVT interlock system that Peter developed. There will also be software interlocks for alarm handling and controls in EPICS. We will compile a list of all components to be purchased (e.g. cRIO system, monitoring sensors) and the price quote for each component.

>> Assembly Structure:
>> To anchor the assembly structure in EEL 124, George informed us that we will be able to drill holes and anchor the structure to the floor. What size bolts would be used to anchor the structure? Also, is there an engineering drawing for the assembly structure that specifies the lift points for the structure and the bolt size? Please let us know. The drawing would need to be reviewed by Hall B Engineering because of the bolt size and each lift will be an engineered list.
