Possibilities of increasing the average power in Ku--range multi-beam TWT
A magnetic focusing system for multi-beam optics was designed, manufactured and studied. A constructive solution is proposed to increase the uniformity of magnetic field in the gap, which should significantly improve the current flow. A multi-beam depressed potential collector has been designed, in which the central part of the collector pole is isolated from the external and connected to the collector body. This solution significantly reduces the reverse current of electrons to transit channel and can considerably increase the degree of recovery in multi-beam devices.
