ABSTRACT:
A satellite thruster system capable of creating a high velocity plasma jet is disclosed. The plasma accelerator, or "railthruster," features a high energy current pulse source and a geometrically configured coaxial or parallel dual-rail ignitor system for higher velocity, and thus more fuel efficient, satellite attitude control. A ratio of a length of the railthruster to a spacing between the rails is at least 3:1.
