Abstract
The main results of High Power Ion Beam (HPIB) generation in the two types of coaxial diodes are given: the first one with axial orange-type insulating magnetic field and zero flux intercepted by HPIB; the second one - with squirrel-cage type cathode and asimutal insulating magnetic field. The first type of diode displayed nonuniform anode plasma generation and consequently lower that awaited average values of convergent HPIB densities (0.3 kA/cm2). The focusing degree in the second case attained 80% of theoretically possible due to cathode slots aberration of HPIB and finite temperature of anode plasma ion source. EPIB densities were 8-10 times higher that corresponding Lengmuir-Blodgett (LB) values1 and attained 1.3 kA/cm2. The investigated diodes are promising for HPIB laser pumping.
