Analysis of propagation of a high-current electron beam from a sectioned plasma-filled diode

Аннотация

We report on the results of analysis of propagation of an electron beam from a plasma-filled diode in the absence of the metal anode between the regions of beam generation and transportation. The diode parameters are 160 kA, 400 kV, and 50 GW. At a distance exceeding 10 cm behind the generation region, a beam current of 100 kA to the target and an energy density of 20 J/cm² are attained for the beam cross-sectional area of about 200 cm². The possibility of varying the beam current and energy density by changing the distance to the target is demonstrated.
