Development of a heaterless hollow cathode for miniature EP systems
Development of a heaterless hollow cathode for miniature EP systems
A Heaterless Hollow Cathode (HHC) has been designed and developed to be integrated into thrusters for LEO and MEO satellites in the mass range of a few hundred kilograms. There are several missions for which a low power (100-500 W) and cost-effective EP system would be beneficial, including small telecom constellations in LEO, small earth observation LEO satellites and Mega Telecom constellations. The BaO-W HHC was tested in diode mode with xenon propellant over a wide range of operating parameters. Significantly, this HHC has demonstrated stable operation for a wide range of currents, 0.9 - 7.5 A, with flow rates below 10 sccm and an anode voltage less than 25 V. For instance, at 7.5 A the HHC established operation in spot mode with as low as 4 sccm and an anode voltage of 12.7 V. The HHC system has a compatible flange to allow for planned integrated coupling tests with the MSL GIE150, a 150 mm Ring Cusp Engine.

Abstract
A Heaterless Hollow Cathode (HHC) has been designed and developed to be integrated into thrusters for LEO and MEO satellites in the mass range of a few hundred kilograms. There are several missions for which a low power (100-500 W) and cost-effective EP system would be beneficial, including small telecom constellations in LEO, small earth observation LEO satellites and Mega Telecom constellations. The BaO-W HHC was tested in diode mode with xenon propellant over a wide range of operating parameters. Significantly, this HHC has demonstrated stable operation for a wide range of currents, 0.9 - 7.5 A, with flow rates below 10 sccm and an anode voltage less than 25 V. For instance, at 7.5 A the HHC established operation in spot mode with as low as 4 sccm and an anode voltage of 12.7 V. The HHC system has a compatible flange to allow for planned integrated coupling tests with the MSL GIE150, a 150 mm Ring Cusp Engine.
