Performance of BNL-TSTA compound cryopump
The Tritium Systems Test Assembly Vacuum Facility at Los Alamos Scientific Laboratory is intended to demonstrate realistic fuel supply and cleanup operations similar to those anticipated on fusion devices. The plasma exhaust gases are expected to be mixtures of helium and hydrogen isotopes which can be pumped most efficiently by cryopumping. A compound cryopump for on-line operation at TSTA using cryocondensation for hydrogen isotopes and cryosorption for helium has been designed by BNL and fabricated by Janis Research. The details of this compound cryopump are described in this paper. The performance of the pump during the pre-delivery testing at BNL, such as the heat load during operation and the pumping speed and pump capacity for helium and hydrogen, are also discussed in detail.
