1COMPACT LOW-IMPEDANCE HIGH-CURRENT ACCELERATOR

electronics posed a number of problems yet remained unsolved. One of them is creating powerful and comparatively compact generators of electromagnetic radiation. In this way great progress is achieved with the use of small accelerators [1] generating millimeter-band oscillations of power up to 40 MW. However, these systems, as with many other devices containing high-current accelerators, have the proper microwave generator sizes significantly smaller than other units composing the high-current accelerator. Therefore, generators of power from 108 to 1010 W should be very awkward. One of the ways to overcome the problem is to employ schemes including a high-current low-impedance accelerator and a microwave generator with the spatially developed electrodynamic structure [2]. Note, that such studies are also promising for applications, since high-current electron beams at moderate voltages are produced there in the simplest way. A diagram of the developed setup is shown i
