October 26, 1960

This giant-sized cathode ray gun, similar to the one in a TV picture tube, is a key research tool in the study of electron beams.

Developed by Dr. Hilary Moss, advisory engineer, of the Westinghouse electronic tube division, the gun is used to learn how closely electron beams can be focused to give images of the greatest density.

Dr. Moss has reached the theoretical limits of beam concentration with the device, and his experiments promise to pave the way to better cathode ray tubes for television and radar.
