Summary
A conceptual design study of neutral beamlines to deliver up to 25 Mwatts of 160 keV neutral deuterium to the proposed West German tokamak, ZEPHYR, was performed at LBL. The study included predicted vacuum behavior of a neutral beamline module, proposed cryopanel design, and a suggested topology for the cryogenic flow distribution systems. The structure will be insensitive to thermal shock and can withstand large pressure excursions. The distribution system is designed for forced flow cryogenic fluid delivery in two circuits, each feeding three neutral beamlines in hydraulic series. The requirements for balancing a large number of parallel circuits and for long transfer lines are thus avoided by this simple distribution system. although the plans for ZEPHYR construction were cancelled, the vacuum calculations, the cryopanel and distribution system design are relevant for the future design of neutral beamlines required for plasma heating of the next generation of magnetic fusion devices.
