Turbulence in hollow cathodes used for space propulsion is believed to play an important
role in anomalous electron transport and ion heating. In this work, the implementation of …

A fully cylindrical Hall thruster prototype was tested in the power range of 30–300 W with the
objective of understanding the behavior of the discharge as a function of input parameters …

Hollow cathodes are used as thermionic emitters in a variety of electric propulsion devices
such as the Hall thruster. This work studies the derivation and discusses the results of a …

Heated thermionic cathodes based on LaB 6 emitters are known to consume a relatively
large amount of power during the heating part of the ignition phase. Miniaturized electric …
