Relativistic magnetrons: Optimization of parameters and modelling of phase locking processes

Calculations of microwave radiation power dependence upon magnetron parameters with a real voltage pulse shape being considered showed fairly good agreement with similar dependencies obtained experimentally. This allowed to choose magnetron optimal parameters in agreement with a high current accelerator as a power source. Next way to increase radiated power is to sum up powers of some pulse relativistic magnetrons. A scheme is based on the principle of non-symmetry allowing a rather strong mismatch of magnetrons eigenfrequencies and being not so critical to a choice of connection line length. The strong coupling provides fast phase locking and high effeciency of the pulse powers addition.
