Abstract

Variants of Ka-band accelerating structures that can be powered by pulses of radiation of nanosecond duration generated by a relativistic backward wave oscillators are considered. It is shown that an average acceleration rate exceeding 120 MV/m can be achieved at a length of 10–20 cm in various structures at a pulse power of 200 MW. This makes it possible to build a fully benchtop system including a compact high-current RADAN accelerator, a relativistic BWO, and an accelerating structure, that can produce electron bunches with particle energies of 10–20 MeV.
