Abstract

The Transverse Field Focusing (TFF) system described here is a prototype for a negative-ion based neutral beam line with possible applications in the U. S. magnetic fusion energy program. The prototype system consists of four main modules: H/sup -/ source, 80 keV pre-accelerator, TFF matching/pumping (M/P) section, and 180 keV TFF accelerator. The first three modules have been installed on the beam line, with the fourth to follow soon. The crucial module, invoking the most difficult (and interesting) physics and engineering issues, is the M/P section. It performs: gas removal from the beam by differential pumping, electron removal, beam thickness reduction to match the TFF accelerator parameters, and beam-edge confinement. The four beamline modules are discussed in this survey, with emphasis on design features of the M/P section.
