Ion beam profile diagnosis method for vacuum arc ion source in sealed tube neutron generator

The ion beam for vacuum arc ion source in sealed tube neutron generator owns some special features, such as multi-particle mixtures, high-intensity beams, short pulse-width, short transport-distance and asymmetric beams. It is related to the design of the vacuum arc ion source and beam optics, which affect the insulation withstand of the device, the life of tritium target, the neutron yield, and so on. It is important to obtain information on ion beam profile in researching of the sealed tube neutron generator.
