Нестабільності замкнутого електронного потоку в динамічному режимі приладів м-типу

Abstract

In dynamic (generating) state of crossed-field devices (CFD), some parasitic oscillations taking a place in non-generating CFDs (e.g., the natural oscillations of electron cloud) are suppressed by a mechanism of spoke’s formation. Instead, other probable sources of noise and instabilities might appear. Revolving convective clouds of a space charge periodically breaking away from the hub and moving to the anode, as well as stable clouds at tops of the spokes, are among the most notable. Their shapes and dynamic internal structures are very similar to the true solitons in a magnetron diode. The physical origins of both items seem as identical
