X-Ray Detector
Model XR-100CR is an x-ray detector, preamplifier and cooler system which uses a thermoelectrically cooled Si-PIN Photodiode as an x-ray detector. Also mounted on the cooler are the input FET and a feedback circuit.
These components are kept at -30°C, and can be monitored by an internal temperature sensor. The hermeitc TO-8 package of the detector has a 1 mil (25µ) Beryllium window to enable soft x-ray detection.
Power to the product is provided by the PX2CR Power Supply. The PX2CR is AC-powered and includes a spectroscopy grade Shaping Amplifier.
The resolution for the 5.9 keV peak of 55Fe is 220 eV FWHM with 12µs shaping time constant (standard) and 186 eV FWHM with 20µs shaping time (optional).
