    Abstract: An imaging system for deployment within a high-radiation environment. The imaging system has an imaging array of photosensitive pixels, each of which contains a sense gate for integrating photogenerated charge during the course of a frame and an amplifier transistor for sampling voltage on the sense gate. Each pixel also contains an inject gate and select and reset FETs, for operation as a charge injection device (CID). Moreover, a circuit including a monitor transistor on each polysilicon layer of the imaging array provides a threshold voltage monitor signal used to compensate a drive signal applied to the array on the basis of threshold voltage shifts induced by exposure to radiation. The array is contained within a remote head that may be evacuated and temperature-controlled and that may contain radiation-hardened drive electronics for generating drive signals upon receipt of a start pulse received from a camera control unit located at a significant distance from the remote head.

    Abstract: An arc tube mounting assembly (1) for a metal halide arc lamp (10) includes frame members (8, 9) for supporting an arc tube (2). The arc tube (2) is supported from above by a looped frame member (8) having a loop (8A) which extends along opposing sides, and across top and base ends (2A, 2B) of the arc tube (2), thus evenly distributing the current to discharge electrode 7, thereby cancelling magnetic forces which could displace the arc from the center of the arc tube (2), resulting in improved lumen maintenance and extended life. A centering circle (8B) of the frame member (8) wraps around the lower ceramic end plug (4), providing coaxial alignment of the arc tube (2) and the tubular outer envelope (11).
