Vacuum current emission and initiation in an LaB6 hollow cathode
Vacuum current emission and initiation in an LaB6 hollow cathode
This paper presents the first investigation of pre-ignition currents and the ignition process in an LaB6 hollow cathode running on krypton propellant. Vacuum and pre-ignition currents are found to be consistent with space charge limited behaviour. A novel, low power ignition strategy with the potential to reduce insert and orifice erosion is also shown.

Abstract
This paper presents the first investigation of pre-ignition currents and the ignition process in an LaB6 hollow cathode running on krypton propellant. Vacuum and pre-ignition currents are found to be consistent with space charge limited behaviour. A novel, low power ignition strategy with the potential to reduce insert and orifice erosion is also shown.
