Model XR-100T-CdTe is a high performance X-Ray and Gamma Ray Detector, Preamplifier, and Cooler system using a 3 x 3 x 1 mm3 Cadmium Telluride (CdTe) diode detector mounted on a two-stage thermoelectric cooler. Also on the cooler are mounted the input FET and feedback components to the charge sensitive preamp. The internal components are kept at approximately -30°C, and can be monitored by a temperature sensitive integrated circuit. The hermetic TO-8 package of the detector has a light tight, vacuum tight 10 mil (250 μm) Beryllium window.
All the critical connections between the detector and preamplifier have been made internally to the XR-100T-CdTe to ensure quick, first time operation by the user. The XR-100T-CdTe is provided complete with BNC connectors and power cable.
