The Role of the Hall Parameter in Magnetohydrodynamic Scaling of Hall Thrusters

Abstract: The Hall parameter (β), the ratio of azimuthal to axial current densities, governs transport and electron magnetization in Hall thrusters. Using a 0-D magnetoydrodynamic (MHD) model and RAIJIN66 experimental data, this study links β to thrust, mass flow rate, and magnetic field. Results show β is a key scaling factor connecting plasma behavior and performance, with high β essential for efficient, stable operation in high density plasma operation.
