Design and testing of low capacitance, 80-kV source cables for MFTF sustaining neutral beam power supplies

Creators

Description

In this paper we summarize characteristics of several cable configurations and consider one design in detail, which consists of twelve, 250 MCM arc cables, ten 4/0 filament cables, and accel, gradient grid, control, and instrumentation cables within a circular split Al pipe. The pipe is air insulated from an outer 24-in. x 24-in. steel duct by utility pin insulators. Varying run lengths require adjustment of the arc inductance by variation of cross sectional cable position. Equilibrium heat transfer analysis indicates the pulse-off time for source conditioning must be somewhat greater than 60 s to keep conductor temperatures below 900C. The results of a high voltage test of a model cable are presented
