Abstract

Designs of a Spherical Tokamak Component Test Facility (CTF) or ST Power Plant feature high plasma currents but a central solenoid is not possible due to the high neutron flux (there being no space for an effective shield). However the design and the equilibrium properties of an ST lend themselves to novel techniques both for obtaining an initial current, and for ramping it up to the operational value. Two methods of initial start-up which do not require use of the central solenoid have been tested on MAST, and are described in this paper. The merging-compression (M-C) scheme, pioneered on START, is routinely used on MAST and can generate ST plasmas of 0.4MA (Section 1). The novel 'Double Null Merging' method (DNM) also appears very promising and plasma current of 340kA has been generated on MAST (Section 2). Copyright © (2005) by the European Physical Society (EPS).
