Results of experimental investigations of low-energy high-current electron beam generation in a plasma-filleduddiode with a long plasma anode and an explosive emission cathode are given. An additional low-current electronudbeam was used to form the long plasma anode by means of the residual or prefilled gas ionization. The long anode isudused simultaneously as the transportation channel with predictable parameters of plasmas. Low-current additionaludbeam is emitted from the thermionic cathode, which can have different geometric form. The solution developedudprovides to create radial profiled plasmas channels of desired plasmas density distribution with a highudreproducibility.
