Abstract

Results of experimental investigations of plasma anode formation and low-energy high-current electron beam generation in a plasma-filled diode with a plasma anode and an explosive emission cathode are given. An additional low-current electron beam was used for the plasma anode (transportation channel) generation by the residual (pre-filled) gas ionization. Measurements of plasma channel parameters in a wide region of experimental conditions confirm that this approach possesses to create radial profiled plasmas channels of desired plasmas density distribution for generation and transport of high-current beams.
