Latest Patents

Nathan B Meezan holds a patent for a "Low power, linear geometry hall plasma source with an open electron drift." This patent describes the operating characteristics of a linear geometry Hall plasma source scaled to operate in the 50 to 100 Watt power range. The design includes two thruster acceleration channels made of alumina and boron nitride. The differences in operation between these two materials are attributed to their secondary electron emission properties. Notably, operation is achieved despite the absence of a closed electron current drift in the Hall direction, indicating an anomalous axial electron mobility due to plasma fluctuations or collisions with the channel wall. The patent also highlights strong low-frequency oscillations in the discharge current, which vary with changes in the applied magnetic field strength. This oscillatory mode's frequency is higher than that observed in larger discharges, owing to the decreased residence time of the propellant within the channel. The linear geometry Hall thrusters allow for simpler magnetic circuit configurations and enable the stacking of multiple thrusters to create modular arrays.
