1 Camera Cooling with Pumped Liquid Nitrogen Richard Schmitt 8/7/06

2 August 7, Simplified Flow Diagram Off-Telescope Liquid Nitrogen Vessel Camera Heat Exchanger Pump

3 August 7, Advantages No reservoir on telescope No sensitivity to orientation No mechanical vibration Straightforward engineering design Simple operation Can be run at 100K Cryocooler vs. tanker supply is economics

4 August 7, Disadvantages Additional 60 watts of heat Cost of pumps about $25k each Possible separator needed on telescope

5 August 7, Development Tasks Need plan and elevation of telescope & dome Need maximum tanker supply pressure Need power and nitrogen costs Analyze two-phase flow, size pipes Design heat exchanger Draw Piping Diagram Assemble and test at Fermilab
