Abstract
The difficulties connected with the development of MM-wave generators of middle and large power in with the shortening of the wavelength. The main cause of this is the decreasing of the geometrical sizes of the elements of slow wave system (SWS) of TWT and, accordingly, the decreasing of transversal cross-section of its floating-drift channel and the increasing of heat loads. The improvement of heat-physics characteristics of TWT is achieved by the using slow wave system with the extensive surface of type of coupled cavity circuit or modification of ribbed structures, working at spatial harmonics. The increasing of the geometrical sizes of the elements of slow wave circuit entails the increasing of the operating voltage, RF-loss, the decreasing of electron flow perveance and electron efficiency. The increasing of the beam perveance and the efficiency in TWT is achieved by the using multi-beam electron flows /1/. At this the increasing of output power, the decreasing of operating voltage and the broadening of operating bandwidth take place. The possibility of the realization of TWT with staircase, slow wave structure to obtain middle and large output power in UHF-region was shown in /1,2/.
