Paper Abstract

When HDTV broadcasting starts, HDTV systems will be required more and more in regions of industrial and medical imaging fields. The authors have developed two types of 2/3-inch MF (Mixed Field) Chalnicon (Cadmium-Selenide photoconductive target) for HDTV systems. One of them, No. N4272, is suitable for a three-tube color camera, and black and white camera. Another, No. N4182, is useful for radiation resistant use ($OM 105 Ren/h). Both N4272 and N4182 feature high sensitivity (N4272: 0.16 (mu) A/lx, N4182: 0.15 (mu) A/lx) and high resolution (1,150 TV Lines) which are good enough for required specifications for HDTV imaging devices. In addition to the features mentioned above, it is remarkable that the maximum operating temperature of N4182 is 185 degree(s)F. Thus it is possible to use it for imaging under such conditions as high radiation and high temperature -- circumstances experienced, for instance, in the nuclear power plant.
