Accelerator IGUR-3 in the mode of electron beam pulse generation

Abstract

The IGUR-3 [V.S. Diyanikov et al., 1995] accelerator has been used to perform a series of experiments to investigate the dynamics of electron beam extracted into air. Several new modes of IGUR-3 operation have been developed. IGUR-3 belongs to the class of direct drive accelerators. The peculiarity of diode allows to form current pulse with duration of 30-400 ns and maximum of outed energy density at the beam axis up to 400 J/cm/sup 2/. The electron beam parameters are: up to 30 kA beam current ; up to 15 kJ beam total energy up to 15 kJ; approximately 5,5 MeV of maximum electron energy; 2,5 MeV of average electron energy. The good pulse parameters reproducibility (/spl plusmn/ 20%) observed in the range of pulse duration from 50 to 200 ns.
