New Camera Tubes for Color Television

A new kind of vidicon-type camera tube, called the Chalnicon,^*™ has been successfully developed, using CdSe photoconductor as a target material. It has these features: Its photosensitivity is as high as 10 to 20 times that of ordinary Sb2S3 vidicons; its spectral response covers the entire visible spectrum, making it most useful as a color TV camera tube; and its low dark current, high resolution and lack of after-image are indispensable characteristics. Presented are the characteristics of several tubes in a variety of tube diameters (18-mm and 25-mm) and electrode configurations (magnetic-focus/magnetic-deflection and electrostatic-focus/magnetic-deflection). Newly developed low-lag tubes are also discussed.
