The XR-100CR/PX2CR or XR-100CR/PX4 system ensures stable operation in less than one minute from power turn-on. The resolution for the 5.9 keV peak of M s). The PX4 is DC powered by an AC adaptor and provides both a variable Shaping Amplifier (.25 ns to 40 0.8 M s2.4 M s > 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 > FWHM (@ 5.9 keV) M s > 1,000100101 Throughput for Dierent Peaking Times2.4 0.8 M s M s4.8 > OCR (kcps) M s9.6 > 55 M s25.6 > Fe is 145 eV FWHM to 260 eV FWHM depending on the de- tector type and shaping time constant (see next page for selection guide).
