Hall Thruster Cathode Flow Impact on Coupling Voltage and Cathode Life

The cathode coupling voltage in Hall thrusters, which is the voltage difference between the cathode and the thruster beam plasma potential, is considered an indicator of the ease with which electrons flow from cathode to anode. Historically, the coupling voltage has been minimized by increasing the...
