Title:
【発明の名称】電子管の集電器
Document Type and Number:
Japanese Patent JP2895083
Kind Code:
B2
Abstract:
According to the invention, the conducting collector wall (23) on which the electrons are collected is surrounded by a coil winding (36) which is supplied with a periodically varying current, creating a slightly divergent axial magnetic field whose amplitude is periodically variable with time. The electron trajectories strike the collector wall at a grazing, nearly tangential angle, broadening the zone of impact, and the zone of impact is swept back and forth along the length of the collector, further spreading the power to be dissipated on a greater surface of the collector. Application to realization of very high power tubes or moderate power tubes with reduced collector dimensions.
