Properties of plasma in an ECR minimum-B trap via numerical modeling

Plasma of a 14 GHz minimum-B source which is based on the electron cyclotron resonance phenomenon, has been studied through a three-dimensional simulation code using a particle in cell technique. In the code, the fast Larmor rotations are calculated with a time step equal to 1/250 of the microwave field period. The space geometry of the electron and ion components as well as the ion spectra both in the core plasma and in the charged particle fluxes which reach the end walls, are determined. The low frequency oscillations of the electron component and the ion plasma component are discussed.
