Integrated circuit techniques have been used to make accurate multicathode electron sources for use in a new high-resolution multibeam CRT. The device features 16 photolithographically patterned oxide cathodes, a common grid, and an integral heater, on a 3.8-mm-square sapphire chip. The electron sources have adequate saturation currents and precise low cutoff voltages. A demountable vacuum system and an emission microscope that images cathodes on the screen of a CRT were constructed to examine the chip during operation.
