Abstract
A 19-V color CRT with 64-kHz scanning was developed for CAD/CAM use. A new gun was designed by a three-dimensional phase space method and with the aid of a three-dimensional beam tracing computer simulation. A newly developed oxide cathode was applied to the gun in order to improve the life performance of cathode emission. The spot size at 2 percent of peak was reduced to 0.8 mm at 200 µA. A significant reduction of misconvergence to 0.2 mm was achieved through the use of a small beam-to-beam gun spacing, a new deflection yoke, and a new frittable getter.
