Abstract : The development of extrinsic infrared camera tubes, using zinc(II)-doped germanium cooled to liquid-helium temperature as a photoconductor, is described. The problems in the growth of the starting material and the preparation of the sensing layers are given. The development and application of a reticulation process yielding increased resolution and thus higher sensitivity for subaperture images, are described and its details outlined. The performance and construction of both the electron optics and the tube envelope are discussed and an analysis of the ultimate performance and limitations of such infrared vidicons is presented. Measured performance data on two tubes fabricated under this contract are given and their performance is compared to the theoretical limit. Recommendations for possible future work are made.
