The Zetatron is a small deuterium-tritium accelerator which uses a reflex-discharge ion source and approximately 130-kV acceleration from a pulse transformer. The dominantly D(T,n) He reaction takes place in an occluder target consisting of a scandium deuterotritide film deposited on a molybdenum slug. The instantaneous energy-deposition rates at the target, the species present in the beam, and the beam profile determine target life and neutron-output characteristics. The target temperatures are calculated for a single pulse and compared to measurements of the thermal profile on a specifically-prepared, thin-target substrate. Target images are shown which illustrate the beam imaging process. The beam is found to consist of an intense spot 2-4 mm in diameter surrounded by a halo approximately the size of the target. The implications of such a beam profile are discussed. Computer codes are used to model the beam and to describe the parts of the tube that control the beam characteristics.
