Television pickup tubes which use a low-velocity electron beam for scanning a photosensitive target offer the possibility of avoiding some of the limitations of devices which use a high-velocity beam. Some of the advantages of the low-velocity beam are: (1) low level of spurious signals, (2) high maximum signal output, and (3) high efficiency of conversion of light into signal. The major problems encountered are: (1) ways to keep the beam in focus and (2) ways to obtain undistorted scanning of… Expand
Television Camera Tubes: A Research Review
Publisher Summary This chapter presents a research review of television camera tubes. In an ideal tube, the sensitivity, resolution, and contrast discrimination would be limited only by theExpand
A New Magnetic-Focus Static-Deflection System for a Sincle-Tube Color Camera
A new magnetic-focus static-deflection system has been developed under a program of exploration of possibilities of designing vidicon tubes to make a focusing and deflection system which will have high quality electron optical characteristics with simple construction and require low power consumption.

Improvements in Image Iconoscopes by Pulsed Biasing the Storage Surface
In storage-type television camera tubes using high-velocity electrons for scanning, such as the iconoscope and image iconoscope, the storage surface is stabilized to an equilibrium potential byExpand
A large-area x-ray-sensitive vidicon
A large area x-ray sensitive vidicon is an alternative to the x-ray image intensifier and television carnera combination (XRWN) currently used to produce fluoroscopic (reai-time) x-ray images. TheExpand
Method of Measuring the Normal Velocity Distribution of Secondary Electrons at Low Primary Bombarding Energies
Experimental apparatus designed to measure the secondary electron emission from solids at low primary electron energies is described. The design permits the determination of the normal velocityExpand

Theory and Performance of the Iconoscope
Field tests have shown the present standard Iconoscope to be a very satisfactory television pickup device. However, from a theoretical point of view the efficiency of the Iconoscope as a storageExpand
The Image Iconoscope
An iconoscope having increased sensitivity is to be desired for purposes of improving studio conditions, making possible more universal outdoor work, and permitting greater depths of focus. The newExpand
