R&D Report 1963-63 : Some investigations into the performance of the CPS Emitron television camera tube. S.J. Lent, A.H. Jones This report describes a series of experiments carried out in order to determine the behaviour of a C.P.S. Emitron television camera tube in the operating conditions encountered in image-transfer standards converters. Some previously undetected aspects of the storage characteristics are described, and beam pulling has been considered in some detail. Finally, the results are related to the behaviour of an image-transfer converter using this type of camera tube.
