Material Selection Process for a Low-Power Magnetically Shielded Hall Thruster

by | Apr 15, 2025 | research papers

“Hall thrusters are a type of electric propulsion device that ionizes and accelerates a plasma to provide low thrust
at high efficiencies. ORB-1-D1 is a low-power magnetically-shielded Hall thruster (≤ 1. 35 kW) developed by the
OUROBOROS project in the University of Alabama in Huntsville Electric Propulsion Club that is designed to run
on krypton and features a center-mounted glow discharge cathode. ORB-1-D1 is estimated to undergo its first test by
May 1, 2025 on argon propellant to determine design feasibility by successful thruster ignition. A large portion of
the development of the system was dedicated to the materials selection of integral components of the thruster,
including the discharge channel, magnetic circuit, and the glow discharge hollow cathode.”
