ABSTRACT:
A method of forming an electron source having a cathode and a permanent magnet having perforated channels extending between opposite poles of the magnet. The perforated channel magnet is formed by pressing an array of pins into a moldable mass of powder confined in a mold, solidifying and magnetizing the molded mass. Electrodes may be provided at each end of the channels. Each channel forms electrons received from the cathode into an electron beam for guidance towards a target. The electron source has applications in a wide range of technologies, including display technology and printer technology.
