Abstract:
In order to summarize the breakdown rules of the rock mixed materials targets with high voltage pulse,the effect of the high voltage pulse on the rock mixed materials block process is simulated through a computer simulation software.Electron beam trajectories and energy density distribution changes from the attack are analysed.The research results show that:under the critical breakdown conditions,the free electron multiplier effect of the electrode end is even more remarkable.The avalanche breakdown shows that the present boundary of the electron beam is narrowing in the input,the electrode tip energy density distribution tends to be focused,and the measured output current peak value is higher.The more narrow the pulse width waveform is,the more effective the rock mixed materials breakdow is related.
