System of strongly coupled relativistic magnetrons

The results of experimental investigations of the system of two strongly coupled relativistic magnetrons with power supply from two independing linear induction accelerators which are continuing at the Institute of Nuclear Physics are reported in the present paper. Two different types of connecting lines (symmetrical and non-symmetrical) between magnetrons were used. The results of the first experiments were presented at the SPIE conference in 1995. Authors investigated symmetrical system of two strongly coupled relativistic magnetrons with power addition in the common load. Net output power of such a system obtained experimentally was 1.9 times higher than that of a single magnetron. In the system of two strongly coupled relativistic magnetrons with power subtraction in the common load the output, power was 25% against the power of a single magnetron. In the present report we discuss the results of experimental investigations of symmetrical and non- symmetrical systems of two relativistic magnetrons with the significant detuning of intrinsic frequencies, and results of power addition and subtraction of magnetron signals in the common load and free space.
