Amptek XR 100T CdTe

The XR-100T-CdTe represents a breakthrough in x-ray detector technology by providing "off-the-shelf" performance previously available only from expensive cryogenically cooled systems.

Features

  • CdTe Diode Detector
  • Thermoelectric (Peltier) Cooler
  • Cooled FET
  • Temperature Monitor
  • Beryllium Window
  • Hermetic Package (TO-8)

 

Applications

  • Medical X-Ray and Gamma Ray Detection: Mamography and Radiology
  • Characterization of x-ray tubes: direct output spectrum, current stability
  • X-Ray Fluorescence
  • Art and Archaeology
  • Portable X-Ray and Gamma Ray Instruments
  • X-Ray and Gamma Ray Research
  • Teaching
  • Nuclear Plant Monitoring
  • Uranium and Plutonium Detection

 

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 mm (or 5x5x1) Cadmium Telluride (CdTe) diode detector mounted on a two-stage thermoelectric cooler. Also on the cooler are the input FET feedback components to the charge sensitive preamplifier. The internal components are kept at approximately -30 ºC and can be monitored by an internal temperature sensor. The hermetic TO-8 package of the detector has a light tight, vacuum tight 4 mil (100 µm) Beryllium window.

All the critical connections between the detector and the 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.
