Model XR-100T-CdTe is a new high performance X-Ray and Gamma Ray Detector, Preamplifier, and Cooler system usinga 3 x 3 x 1 mm³ Cadmium Telluride (CdTe) diode detector mounted on a thermoelectric cooler. Also, on the cooler are mounted the input FET and feedback components to the Amptek A250 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.
In order to facilitate the use of the detector, Model PX2T was developed to provide the DC Voltages needed to operate the XR-100T-CdTe, and the signal processing through the Shaping Amplifier and Rise Time Discrimination (RTD) circuits. The signal output from the PX2T can be connected directly to a Multichannel Analyzer (MCA).
