Paper Abstract

The objective of the work is to study effect of the rise time of voltage pulses ranged from 15 ns to 1.5 μs on generation of runaway electron beams and X-ray radiation in nonuniform electric field. Three setups and different pressures of air, nitrogen, argon and helium were used. The experiments on the setup #1 have confirm that there are different regimes of generation of runaway electrons and X-ray emission when voltage pulses with a long front duration are used. When voltage pulse amplitude reached 150 kV at a pulse rise time of 1.5 μs, the new results was obtained on the setup #3. At this setup, a runaway electron beam was registered by a collector in argon, air, and nitrogen at pressures up to ≈ 12.5 kPa. When using helium, a supershort avalanches electron beam (SAEB) was obtained at a pressure of 100 kPa.
