Improved High Resolution Electron Gun for Television Cameras

The resolution performance of a television camera is determined by the cascaded response of a number of stages, each of which is the optical equivalent of a low-pass filter. One component which is common and important in all cameras is the aperture presented by the scanning electron-beam. By mechanically smoothing the oxide coating of the cathode, the intrinsic resolution capability of the beam in an image-orthicon electron gun has been nearly doubled. Descriptions of the processing technique and some experimental results are included.
