The BHT-1500 from Busek is a Hall Effect Thruster with a nominal thrust of 101 mN and a specific impulse of 1710 seconds. This thruster has a discharge power of 1500 W and a throttle range of 1000 W - 2700 W. It uses Xenon, Krypton, and Iodine as a propellant. The thruster features an innovative center-mounted cathode and uses novel design features like a two-piece “composite” anode and shortened dielectric channel which makes the thruster less sensitive to vacuum facility background pressure and exhibits less plume divergence. It has a mass of 6.3 kg and a cathode mass of 0.3 kg.
