Abstract

The Princeton Beta Experiment-Modified (PBX-M) Pellet Injector Project, which provides for the fabrication, installation, and operation of a pellet-injector fueling system on the PBX-M tokamak experiment, is described and its operation is discussed. The system consists of an eight-barrel pellet gun, a pellet transport facility, and a control system. The gun is an eight-shot pneumatic assembly designed and fabricated at the Oak Ridge National Laboratory (ORNL). The pellet transport and control facilities were designed, fabricated, and installed by the Princeton Plasma Physics Laboratory (PPPL). The integrated pellet-injector system has been installed on PBX-M and is operational for use in plasma experiments. Initial tokamak operation utilizing a single gun provided a high rate of successful pellet formation
