Model XR-100CR is a high performance X-Ray Detector, Pre-amplifier, and Cooler system using a thermoelectrically cooled Si-PIN Photodiode as an X-Ray detector. Also mounted on the 2-stage cooler are the input FET and a novel feedback circuit. These components are kept at approximately -55հC, and are monitored by an internal temperature sensor. The hermetic TO-8 package of the detector has a light tight, vacuum tight thin Beryllium window to enable soft X-Ray detection. Power to the XR-100CR is provided by either the PX2CR or the PX4. The PX2CR is AC powered and includes a spec-
troscopy grade Shaping Amplifier with fixed time constant (6 4.8 M s9.6 M s25.6 >
