Present report refers to the problem of the study of charged particle dynamics in the Penning-Malmberg-Surko trap. Various models of particle dynamics describing the magnetron and cyclotron motions are considered. Representation of the solutions in the form of a series is used for the magnetron motion. The problems of the stability of the magnetron motion are investigated.

The considered source of triode type produces intense radial converging electron beam for irradiation of cylindrical targets. As an electron emitter an explosive plasma cathode is used. The role of initial transverse velocities of electrons, defocusing effect of the controlling grid, the beam self-magnetic field, electron and ion emission from the controlling grid, backscattering of electrons and ion flow from the target is analyzed. Conditions for achieving required electron beam parameters (the electron kinetic energy - 120 keV, the beam energy density on the target 40 J/cm2 on a maximum possible length of the target surface) were determined.
