Abstract
Accelerated charged particles are provided by inductive amplification of particle energy in connection with a deflagration-mode plasma discharge. The deflagration mode discharge tends to increase particle energy relative to other operating modes. Inductive amplification of particle energy further increases output particle velocity. Inductive amplification can occur by formation of a current loop in the plasma discharge, and/or by a sudden increase in inductance due to collapse of the current distribution of the plasma discharge. Applications include particle therapy and production of radio-isotopes.
