INFLUENCE OF THE RELATIVISTIC ELECTRON BEAM SPECTRAL CHARACTERISTICS ON THE INSTABILITY DEVELOPMENT PROCESS AT NEARLIMITING CURRENT

INFLUENCE OF THE RELATIVISTIC ELECTRON BEAM SPECTRAL CHARACTERISTICS ON THE INSTABILITY DEVELOPMENT PROCESS AT NEARLIMITING CURRENT

The paper presents the results of the numerical research of the influence of spectral characteristics of the relativistic electron beam, restricted by a spatial charge, on the instability development at near-limiting current. The beam system model is described permitting to calculate with minor erro...
