“…As can be seen in Fig. 4 and 5, the anode voltage decreases when the current increases and it stays in the [10][11][12][13][14][15][16][17][18][19][20][21][22][23][24][25] V range, in agreement with outcomes of preceeding studies [15,17,23,24]. The self-heating regime of hollow cathodes depends on the discharge current magnitude [7].…”

“…Two geometries have been selected: planar and cylindrical. They are the most common geometries for cathode discharge characterization in the electric propulsion field [16][17][18] . Two anodes have a planar geometry: one is a plate while the other one is a disk.…”

The characterization of an electric propulsion device cathode is performed in the so-called diode configuration with an external anode. The anode acts as a physical boundary for the cathode plasma discharge; therefore, it influences cathode operation and performances. In this study, four different anodes—namely, a disk, a plate, a long cylinder, and a short cylinder—have been used with a flat disk LaB6 emitter 5 A-class cathode to examine the anode geometry impact on cathode discharge properties. Current–voltage curves, discharge oscillations, electron parameters, and ion velocities have been measured for currents in the 2 A to 12 A range and xenon mass flow rates varied from 0.4 mg/s to 1 mg/s with a fixed cathode-to-anode distance. The set of results clearly supports the fact that the anode geometry strongly influences the cathode characteristics both at the macroscopic and the microscopic scale.

“…This requires heater devices capable of delivering high temperatures which may lead to greater risk of failures [7]. This last aspect is of great importance when developing high power Hall thrusters and it is therefore under considera-35 tion by several research teams [7,8,9].…”
