What is it about?
Results of preliminary tests on a direct current neutralizer operated in ExB discharge. Tests were performed with argon. The results include extraction efficiency - extracted electron current versus input current - and energy efficiency - extracted electron current versus total input power.

Why is it important?
This neutralizer does not rely on emissive surfaces - contrary to conventional hollow cathodes - and, thus, can potentially operate with a wide variety of propellants.
