The silicon diode array camera tube
WebA camera tube employing a silicon target with a diode array which is covered with a resistive layer or sea on the side facing the electron beam. The resistive sea consists of a layer of bismuth oxide which protects the silicon target from damage by xrays while minimizing charge build-up on the insulating layer between diodes which would otherwise prevent … WebJan 1, 1980 · An array consisting of 22 diodes was modelled. Each diode was 10 p m long, and the diodes were spaced 15 p m apart. The sampling interval, At, was 10 psec. To …

WebThe specification describes processes using ion implantation for preparing silicon diode array targets for video camera tubes. Bulk silicon prepared in the conventional way has sufficient nonuniformity over the target area to produce contrast patterns in the video output. This effect can be eliminated by initially preparing high resistivity bulk material … WebThe silicon target plate thus formed is typically 0.003 cm thick, 1.5 cm square having an array of 540 × 540 photodiodes. This target plate is mounted in a vidicon type of camera tube. Scanning and Operation The photodiodes are reverse biased by applying +10 V or so to the n + layer on the substrate.
WebThe tubes were vacuum processed as an elevated bake temperature of 400°C, which assures much longer cathode life. The tube performance has been measured to be much … WebA new electronic camera tube has been developed for Picturephone® visual telephone applications; with minor modifications it should also be suitable for conventional …
