[Clas12_rich] RICH cooling, interlocks and assembly structure

[George Jacobs]

Please find attached pdf file showing the cooling circuit and explaining 
the associated power supply interlocks.

This is a preliminary diagram since  system min/max operating parameters 
have yet to be determined.

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.

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.
