The development of a high-definition cathode-ray tube using a carbon-fibre field-emission electron source

Abstract

Details of a current-efficient field-emission electron gun suitable for use in a cathode-ray tube are given. Such a gun, using a carbon-fibre emitter, was subsequently used as the basis for developing a prototype CRT whose performance is shown to compare very favourable in most respects with the corresponding conventional device employing a thermionic cathode. However, intensity fluctuations in the display remain to be eliminated before it can be adopted as a practical device.
