Arc Lamps

Arc lamps are high-intensity electric lamps that produce light by an electric arc between two electrodes. In space and astronautical engineering, arc lamps are used in various applications such as spacecraft propulsion, welding, and lighting. In spacecraft propulsion, arc lamps are used in ion thrusters, which generate thrust by accelerating ions using an electric field. In welding, arc lamps are used to create an electric arc between the welding electrode and the workpiece, which melts the metal and creates a weld. In lighting, arc lamps are used in space telescopes and other scientific instruments to provide a high-intensity light source for imaging and spectroscopy.
