Abstract

The ion trajectory in a hollow cathode discharge plasma to which a magnetic field combined a solenoid and a Helmholtz coil is applied is analyzed, and the ion energy distribution at the cathode or the end of the device is examined. It was shown that the ratio of particles lost at the end of the device and those lost during collision with the cathode can be changed by varying the length of the cylindrical cathode.
