7. Utilities at Bulkhead Plate: LSE-64
380VAC 3-phase power
Stepped down to 220VAC single-phase
DAQ Fibers (12 multi-strand)
Using 1 of the DAQ fibers

9. Interface to Refrigeration Pathfinder
Not specifically covered in this review
Mechanical volume (Ø940mm x 771mm) for pathfinder at back of utility box
Utilities needed for refrigeration pathfinder
Turbo pump and controller
Ion pump and controller
HCU
Cryo and cold system heaters
Vacuum gauges, readout and power supply
RTDs and digitization electronics
Pressure transducers and digitization electronics
VQM
Gate valves and pneumatic controls for valves
Protection system?

10. Interface to Refrigeration Pathfinder
Very little work on refrigeration pathfinder currently
Interface to Utility Box not well defined
Based on current layout with “I&T” HX in the ComCam model, refrigeration team confirms 3 circuit system will fit
LCN generated for FY18 funding of refrigeration pathfinder
Design to begin in FY18

11. Software Interface
Components within utility box specified to be same as Camera utility trunk components wherever possible
For the same components, CCS will already have control scripts
For new/different components, CCS will need to create new controls
Current architecture has one HCU to control the cryostat and another HCU to control the filter changer and shutter
Camera utility trunk has many more HCUs
Control logic for startup/cooldown most likely different from Camera
Startup/cooldown procedures for the cryostat are being defined now in TS7/TS8
CCS and DAQ can accommodate ComCam on the TMA and Camera testing in the maintenance area (or vice versa)
