Electrode
In space and astronautical engineering, an electrode is a conductor through which an electric current enters or leaves a vacuum tube, ion thruster, or other electrical device in space. Electrodes are used in various space applications such as electric propulsion systems, plasma thrusters, and ion engines. They are typically made of materials that can withstand high temperatures and corrosive environments, such as tungsten, molybdenum, or graphite. The shape and design of the electrode can greatly affect the performance of the device, and engineers must carefully consider factors such as the electrode's surface area, temperature, and erosion rate. Electrodes are crucial components in many space missions, as they provide the means for generating and controlling electric fields and plasma.
