Abstract:

This report describes a program of study and investigation which was carried out to determine the optimum crystal materials and detector mount configuration for a low noise millimeter detector in the frequency range of 280 plus or minus 20 gc. Fifteen semiconductor crystal materials were evaluated for tangential sensitivity and video resistance. Of these materials, silicon, lead selenide and bismuth telluride exceeded the sensitivity goal of 10 to the minus 10th power watts for a band-width of one cps and unity signal-to-noise ratio. Material samples and detector mounts were provided as deliverable items to the contracting officer. Sufficient data were obtained for each crystal material to provide a good statistical representation of performance. In addition, the following tasks are reported on Measurement of the performance of a Raytheon Photoelectric Millimeter Wave Detector at 290 gc. Evaluation of bi-metallic contact performance using pointed whiskers on clean metal posts. Author
