Нестабільності замкнутого електронного потоку в статичному режимі приладів м-типу

Abstract

Despite numerous attempts to explain the causes of increased noise level in crossed-field devices (CFD), there is no clear understanding of the physical phenomena generating additional noise in crossed fields. Here, an attempt is made to numerically simulate and describe some parasitic oscillatory processes in the re-entrant electron flow in non-generating (static) state of CFDs. The results were obtained using the TULIPgm code, designed for full-format transient and spectral particle-in-cell CFD modeling. Spatio-temporal interpolation of the fields was performed using the new PWS method.
