摘要：

The thermal shield system provides the required reduction of both total and local thermal loads to the cold structures operating at 4.5 K. The most complex thermal shield component is the vacuum vessel (W) thermal shield (VVTS) located in a narrow gap between the toroidal field coil system and the W. The paper concentrates on specific thermal shield issues, such as the VVTS over-all design including inboard support system and neutral beam ports, details of the VVTS sub-assembly and assembly procedures, section joints, design and efficiency of thermal shield component interfaces, etc. It also presents results of cryovacuum, thermal-hydraulic, seismic and structural analyses.
