Development and characterization of a diverging cusped field thruster and a lanthanum hexaboride hollow cathode
… 32°. In addition to the DCF thruster, a small lanthanum hexaboride (LaB6) hollow cathode has been developed for use with plasma thrusters within the MIT Space Propulsion Laboratory.

The application of the Kelvin probe in materials science.
… lowest work function of ~2.54eV was measured on lanthanum hexaboride, LaB6. The process of thermal and hyperthermal surface ionisation (SI, HSI) as well as the generation of hyperthermal molecular beams is discussed and a model of the surface ionisation process is developed to estimate its …

Characterization of a Low Current LaB6 Heaterless Hollow Cathode with Krypton Propellant
A first-generation LaB6 heaterless hollow cathode with a flat-plate anode is experimentally investigated. The cathode is characterized using krypton as propellant at varying flow rates, discharge currents and cathode-anode distances. Voltage probes, used to make direct voltage measurements in the …
