TPX vacuum vessel heating and cooling system

The Tokamak Physics Experiment (TPX) machine is a compact steady state fusion device. The TPX vacuum vessel provides the vacuum boundary for the plasma and mechanical support for internal components. The vacuum vessel itself and internal components are subjected to large heat loads during bakeout and plasma operation. A dual function heating/cooling system has been designed to satisfy thermal requirements for the vacuum vessel and in-vessel components. A successful Conceptual Design Review (CDR) was held in March 1993. Important parameters presented at the CDR are described herein.
