An overview of the achievements by the authors is presented on the topics of the long pulse,high efficiency HPM sources. The overview and analysis of several frontier fields on intense current electronics are also given. Several kinds of phase locking,such as the cases driven by external signal,mutual drive in the two oscillators,serial connection oscillators and central connection oscillators are studied. The phase locking of external drive case and mutual drive in the two oscillators of the millimeter wave vircators are analyzed and the results of numerical simulations are in good agreement with those of analysis. The properties of hollow cathode plasma electron gun are studied,which can generate long pulse (》1μs),high current density (》50A/cm2) electron beam. The interaction principle and key technology of a new kind long pulse,high efficiency HPM source-plasma assisted slow wave oscillator, which do not need external magnetic field,are studied.
