Secondary electron conduction camera tube for space applications
Abstract:
A camera tube based on the SEC (secondary electron conduction) effect has been developed for space applications. The background to the initiation of this development is briefly mentioned and anticipated applications are reviewed. These comprise the use as a detector in astronomical instruments (cameras and spectrographs), in a star field camera, and in special instruments for earth observation. The tube construction is described where it concerns the modifications made to the original standard tube produced by the firm Heimann GmbH. Finally, a first assessment of the tube performance is summarized as measured in a standard test facility operating in the standard European scan format.
