Outline of Final Research Achievements

A plasma simulation code was developed to investigate plasma flow of hollow cathodes. The model treats the heavy particles (neutrals and ions) and electrons as particles and fluid, respectively. The developed code was validated through the comparison with the preceding measured data within the cathode, i.e. the simulated electron number density is in good agreement with the experimental data obtained by other group. Our own hollow cathode was also manufactured, and experiments in a diode mode were also conducted in the current range of 10-50 A. Then, mode transition from plume to spot mode was observed for a mass flow rate above 30 sccm. The simulations under the same condition as our cathode were also carried out, and it was found that the self-heating is sustained mainly by the ion bombardment.
