Abstract
A high current plasma electron emitter based on a miniature plasma source has been developed. The source is characterized by a high electron emission current density and emission current, small size, and low impurity content. The emitting plasma is created by a pulsed high current gas discharge. The source is biased negatively to extract electrons. Electron currents of the order of 1 kA at a bias voltage of about 100 V are obtained. The source has a simple design and has proven to be very reliable in operation. Extensive studies of the effect of the source geometry and materials have been conducted.
