Experimental results on the properties of an ion beam produced in a magnetic-insulation diode with a field B/sub r/ and on the transport of this beam in vacuum in a guiding magnetic field are reported. It has been shown by means of various diagnostic procedures that the distribution of the electron loss to the anode (this loss is responsible for the plasma production) depends on the strength of the insulating magnetic field. The production of the intense ion beam begins in the interior region of the anode and is delayed no more than 10 ns with respect to the voltage pulse. It has been established experimentally that the reason why the density of the ion beam which is produced is significantly higher than the Child--Langmuir value is a decrease in the effective length of the anode--cathode gap due to the moving anode and cathode plasmas. The experimental results on the transport of the intense ion beam show that the current neutralization and the charge neutralization of the ion beam are not complete. The motion is of a spindle-shaped nature, because of the B/sub r/ and B/sub z/ components of the magnetic field. The experimental result agree well with the results of numerical calculations.
