10000-Ignition-Cycle Investigation of a LaB 6 Hollow Cathode for 3-5-Kilowatt Hall Thruster

In this Paper a newly designed heaterless LaB6 hollow cathode is studied for 10,000 ignition cycles. The current-voltage characteristics and upstream pressure of the hollow cathode are monitored during this procedure, and a destructive analysis is made after 10,000 ignition cycles. It is found that...
