A periodic-pulse ion accelerator based on low-current vacuum-arc discharge is described. It is shown that stable conditions for ion-beam generation are achieved for a residual gas pressure in the accelerator chamber of <10-5 torr and a pulse repetition rate of >5 Hz. The accelerator can generate beams of ions of conducting materials at an accelerating potential of up to 50 kV, an ion charge of 1-4, a beam current of 0.1-1 A, a pulse duration of 10-103 μsec, a pulse repetition frequency of up to 103 Hz, and a beam diameter of 0.2-20 cm.
