Currently there are generators of intense ion beams of nanosecond duration. For the purpose of the injection such ions into a linear accelerator the formation of a sequence ~10² ion bunches of a duration of 20 ns, a current of ~100 mA total current pulse duration of about 1 μs is considered in this work. In this case, bunches of highly charged ions (HCI) of aluminum are generated by field emission by applying a voltage of 400 kV, a duration of 50 ns at a block of aluminum emitters, spaced along the axis of the injector. The injector consists of a sequence co-axial emitters, a grounded accelerating grid and a retarding-and-turning grid. Trough the retarding-and-turning grid a current is passed from the current pulse generator, which creates an azimuthal magnetic field directing HTI along the axis. The analytical calculations that determine the parameters and confirming the possibility of the technical realization of such a device are shown.
