The measured performance of a cylindrical Hall thruster operating at 100W input power was reported. A cylindrical geometry Hall thruster (CHT) was developed for low power applications. It has a cylindrical geometry which is critical for electron confinement because there is a large axial gradient in magnetic field over the cylindrical part. A CHT consists of a boron nitride channel, an annular anode, two electromagnet coils, a magnetic core and the propellant Xenon gas. Gas was injected through the anode into the short annular region of the thruster. Thrust was measured using a Variable amplitude hanging pendulum with exchange range thrust stand. Finally, it was concluded that CHT can easily be scaled down as per the power requirements while the conventional Hall thrusters cannot be because of their annular geometry and magnetic field optimization problem.
