Abstract : The development and improvement of extrinsic infrared vidicons using copper-II doped germanium cooled to liquid-nitrogen temperature as a photoconductor are described. The problems in the preparation of the sensing layers and detailed processing schedules of individual layers are presented. The successful development of a reticulation process yielding increased resolution and thereby higher sensitivity for the detection of point targets, is described and its details on limitations are outlined. The performance and construction of both the electron optics and the tube envelope are discussed and an analysis of the ultimate sensitivity of such vidicons is presented. Measured performance data on two tubes fabricated under this contract are given and their performance is compared to previous tubes without a reticulated sensing layer. (Author)
