PI-MTE is an innovative, high-sensitivity digital x-ray imaging system designed to deliver scientific performance inside high-vacuum chambers over long operation times. The PI-MTE incorporates a back-illuminated CCD without AR coating for very low-energy x-ray detection. With 20 x 20-micron and 13.5 x 13.5 micron pixels and 100% fill factor, this system offers a large imaging area with very high spatial resolution and dynamic range. The thermoelectrically cooled design features printed circuit boards thermally linked to the circulating coolant to provide reliable operation inside the vacuum chamber. This is important because CCD support circuitry implemented on normal circuit boards will overheat in a vacuum. This is true even for the very low power circuitry used in preamplifiers. This camera has also been optimized for minimum size, so that it can be positioned most easily in the limited space of an experimental vacuum chamber. The compact size and flexible tubing facilitate the positioning of the detector in limited space or on a movable arm to image a subject from more than one direction. The camera only supports water cooling, and there is no shutter. (Pulsed illumination should be used, synchronized with the readout of the camera.) The camera can be provided with vacuum-compatible electrical cabling and coolant hoses and with corresponding feedthroughs mounted on a vacuum flange.

Note:
these cameras can be used for either optical or X-ray detection. In the case of X-ray detection, it may be necessary to add some X-ray transparent but optically opaque material in front of the CCD. Contact the Princeton Instruments factory to discuss your specific requirements. These cameras are expressly not for medical use. Also note that these cameras use their vacuum environment for thermal isolation of the cooled CCD, and for preventing condensation on it. Thus they cannot be operated in air, so they should be turned off and allowed to warm up before the vacuum chamber they operate in is vented.
