A Model of Charged Particle Accelerations in the Plasma Focus

Abstract

A hybrid plama diode model with rapid current expansion is proposed for charged particle accelerations in the plasma focus discharge. It is shown that the model leads to strong induced electric fields sufficient for MeV order accelerations with a short acceleration time less than or around 1 nsec and a short acceleration length around 1 mm. A simple scaling for resultant energies of charged particles by the model is discussed and compared with results of a simulation of the plasma focus discharge. A possibility of connection of the model with one of the origins of cosmic rays is discussed.
