Abstract :
The paper reviews some problems of physical electronic of high power gyrotron and possible solution, results of calculation and experimental study of gyrotrons for fusion operating in a wide frequency range and at the 1 MW power level. Effects of beam potential depression and mode interaction (competition and cooperation) in gyrotrons, methods of mode selection including multibeam and complex cavity systems are presented. The dependence of gyrotron parameters on the beam current and magnetic field is analyzed. The experimental results are compared with the calculated data
