This article summarizes the research results of the authors in the area of new technologies for long pulse high efficiency HPM sources. Several frontier fields of the relativistic electronics of the strong current are analyzed and reviewed. The main and secondary phase locking of the cavity oscillator, the equivalent phase locking of the mutual coupling oscillator and the ring-coupling mutual coupling oscillator are studied. The central coupling net-like mutual coupling oscillation The principle and method of equal phase-locked, the main-slave phase-locking and equivalent phase-locking of the millimeter-wave virtual cathode device are analyzed, and the numerical calculation and analysis are in good agreement. A new long-pulse hollow cathode plasma electron gun and its Characteristics of the electron gun can produce long pulse (“1μs) high current density (≥ 50A / cm2) electronic injection; analysis of a new type of long pulse, high efficiency HPM source ─ ─ plasma-assisted slow wave oscillator mechanism, the key Technology and its implementation, it does not require an external magnetic field and has the capability of long pulse (”1μs) high efficiency (15% ~ 25%) and high average power (> 1kW).
