A previously developed computational method, which treats all particles in plasma kinetically, is applied for a study of effects increasing voltage beyond wellestablished range around 300V (for Xenon). Although some additional code development still necessary to improve absolute accuracy, several important trends and are identified through these calculations. If magnetic field kept constant, overall anode efficiency found increase first, peak about 600V, then decrease higher voltages. On other hand, if B optimized each voltage, increases continuously with V. The detailed physics behind this behavior identified. secondion fraction (Xe/Xe) rapidly but nearly saturates further increases. electron temperature approaches proportionality since metallic walls (TAL style) were assumed, secondary emission was ignored.
