Description
The surface flashover ion source based on MEMS technology is the component of the chip type neutron generator. In this paper, patterned titanium films are prepared on polished ceramic substrates and surface flashover ion source samples are obtained. The stability of the surface flashover ion source is studied by analyzing the extraction ion current. The relative standard deviation of ion current is 10.0%, which shows that the arc discharge operates stably. The ratio of ion current to arc current is 3.6%. The electrode ablation characteristics of the surface flashover ion source are obtained by laser confocal microscope. Finally, based on the experimental results, the discharge mechanism of surface flashover ion source is revealed.
