COMPASS VACUUM VESSEL ASSEMBLIES
COMPASS is a compact toroidal experiment which is designed for flexible operation as a circular or D-section tokamak or as a reversed field pinch with a circular cross-section plasma. The physics objectives are to establish conditions for the active control of disruptive instabilities, operation of a circular tokamak at low q (< 2), optimisation of beta using a non-circular plasma cross-section, the possible implementation of a near continuously operating tokamak and operation at ultra low q in the pinch mode. To be able to cover this operating range it is necessary to have the choice of either a circular or a D-section vacuum vessel and to be able to change the configuration of the poloidal field windings. The circular section torus will be the first to be installed, the other of D cross- section, which will be used for the greater part of the COMPASS experimental programme, will be installed later. This paper describes the design and method of construction of the two vessels and how the scientific and technical requirements are achieved.
