WebCondensable Propellant Hall Thrusters. All commercial Hall-effect thrusters use gaseous propellant – usually xenon or krypton – to produce thrust. At the Isp Lab we are pioneering the use of exotic propellants that expand the operating range of Hall thrusters. We have focused on metal propellants such as bismuth, magnesium, and zinc. WebThe low Isp ion thruster operation is based on tests on the 30cm Ion thruster by Patterson. 7 The state-of-art Hall and ion thrusters will be limited to specific impulses in their state-of-art ranges, 1500 seconds and 3000-3800 seconds, respectively. These state-of-art thrusters are loosely based on the SPT-100 Hall and the XIPS-25 ion thrusters.
