Characteristics of Pulsed Ion Beams Extracted from Inverse Reflex Tetrodes

Abstract

Pulsed ion beams were extracted from inverse reflex tetrodes and their characteristics were investigated in detail. The inverse reflex tetrodes were fed by a coaxial blumlein line, which was charged by a marx generator. Current neutralized proton beams with a peak energy of 180 keV were obtained with the extraction angle of about 2-3 degree. The value of proton beam current was almost 400 A, and the maximum flux density was 40 A/cm². Virtual cathode formations and electron reflexing effects were also assured.
