Performance characteristics of the DIII-D advanced divertor cryopump
1993
A cryocondensation pump, cooled by forced flow of two-phase helium, has been installed for particle exhaust from the divertor region of the DIII-D tokamak. The Inconel pumping surface is of coaxial geometry, 25.4 mm in outer diameter and 11.65 m in length. Because of the tokamak environment, the pump is designed to perform under relatively high pulsed heat loads (300 W m/sup -2/). Results of measurements made on the pumping characteristics for D/sub 2/, H/sub 2/, and Ar are discussed.
