APPLIED RESEARCH ON HIGH RESOLUTION CAMERA TUBES.

Abstract : Continued research is reported on positive-grid electron guns. The new effort is concerned with cathode, electron gun and electron beam problems; and with the development of a system for cycled operation of a camera tube of the image orthicon type. It is also a continuation of work in developing a target structure consistent with the requirements for a high sensitivity camera tube capable of 1500 television lines per inch at 50 percent sine-wave response over a 2 x 2 in. format. The handling procedures for processing targets was further developed and refined. Work in this area is continuing. Special testing equipment was built and assembled in order to test and evaluate the tubes being built under this contract. (Author)
