The sensitivity of a television camera system is limited by noise generated in the pick-up tube and in the amplifiers of the system. This work seeks and examines the effects of all the noise sources involved, and elaborated in particular on the noise sources of a Vidicon and of an SEC camera-tube. The overall system is given thorough theoretical attention the two tubes mentioned have also been investigated experimentally. The results provide means and measures by which the sensitivity of a camera system can be rated also, more significantly, by revealing the causes of noise they provide the understanding to be used to further improve the sensitivity of television cameras. Part B gives a survey of earlier work completed under the contract. It discusses secondary emission noise, noise in transmission secondary emission, in image intensifiers, in channel multipliers, and a survey of theorems on noise in television pick-up tubes. In all these cases full reference is made to earlier reports and or published papers. Author
