Abstract

The high voltage accelerator of the diode type for operation in the open air are described and several experiments on nonsinusoidal HF-radiation which have been carried out with this installation are represented. Mounting of the accelerator out of the building is conditioned by some applications on the electromagnetic fields generation and their propagation in the open space. The beam parameters are the following: maximum energy is 1.2 MeV, maximum current 10 kA, and pulse duration is 5-15 ns. The nonsinusoidal oscillations like a sequence of separate pulses with alternative signs are registered by a horn antenna at a distance from 50 m to 1 km. The simulation of beam electrons radiation in a oscillating virtual cathode has been performed to explain the mechanism of observed generation
