Plasma-beam processes in systems with plasma layers

A change of metal anode in high-current high voltage diodes to a plasma layer widens its\´ possibilities. Increase of electron beam generation duration, controllability of initial diode perveance, high-current generation in the device of "Vircator" type with radiation spectrum, different from the vircator with a metal anode, possibility of generation of accelerated electron-ion fluxes, etc. are the discovered effects. Application of plasma layers in electron beam drift tubes gives additional regime possibilities. Investigation results, including new results on electron-ion flux generation in the system of a coaxial plasma-filled diode are presented in the paper.
