Operation of a 2-phase return dewar in a satellite refrigerator
In late 1986 a 100 liter liquid helium phase separator/dewar was designed for use in the Tevatron satellite refrigeration system. Installed on the low pressure return side of the helium circuit between the tunnel return and the exchanger cold end, this vessel was to provide phase separation for a future centrifugal cold compressor installed immediately downstream. Additionally, the vessel by itself would buffer the satellite refrigerator's coldbox from cryogenic system upsets occurring in the tunnel during Tevatron operation. By mid-1988 a prototype had been constructed and approval received to install the 2-phase return dewar in the A1 refrigerator. This paper describes both vessel and refrigerator performance during this test period and draws conclusions with regard to the benefits of such a device in a satellite refrigerator.
