We report the high-gradient acceleration of electrons driven by a subnanosecond pulse of Ka-band Cherenkov superradiance (SR). The experiments are carried out in a combined “generator-accelerator” scheme, powered by two electron beams from a coax

Recently, gradients on the order of 1 GV/m have been obtained with single-cycle (∼1 ps) THz pulses produced by the conversion of high peak power laser radiation, in nonlinear crystals (∼1 mJ, 1 ps, up to 3% conversion efficiency). Such high inten

The frequency multiplication effects in high-power free-electron masers (FEM) with Bragg cavities were studied to provide the advance of the oscillators into short-wavelength bands. Theoretical analysis of frequency-multiplying FEMs was carried out w

Results of numerical calculations and experimental investigations of an active Ka-band microwave pulse compressor are presented. The compressor is based on a running-wave, three-mirror, quasioptical resonator utilizing a diffraction grating whose cha

Experiments to investigate copper surface fatigue caused by pulsed rf radiation were carried out using the 30 GHz free electron maser. The copper surface of a special test cavity was exposed to 15–20 MW/150–200 ns rf pulses with a repetition rate

A compact rf pulse compressor, fed by a phase-modulated pulse, is described for producing high-power flattop pulses at Ka-band. The compressor consists of a single axisymmetrical cavity operating in a combination of TE_{0n} modes (n=1, 2, 3), that ha

The millimeter wave all-metallic accelerating structure, aimed to provide more than 100 MeV/m gradient and fed by feeding RF pulses of 20-30 ns duration, is proposed. The structure is based on a waveguide with small helical corrugation. Each section
