Neutralization and focussing of pulsed beams with high current densities
Abstract
The intense pulsed ion beams with energies about 70 keV produced by the multiplate chamber (MPC) under low gas pressure are extracted from the cathode hole. High power densities are evidently proved by the craters with diameters about 15 micrometers or less on the surface of metallic targets. The major processes of beam production and propagation could be explained by the factors of the field escalation effects in the MPC; fast charge neutralization by the simultaneous introduction of electrons on surfaces in close proximity to the beam; bunching of time of flight and focussing of the plasma lens. It is expected that the processes described above could be used experimentally for simulation of intense pulsed ion beams propagating in the low gas pressure.
