Also mounted on the 2-stage cooler are the input FET and a novel feedback circuit. These components are kept at approximately -55°C, 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 the PX5 Digital Pulse Processor and Power Supply. The PX5 is DC powered by an AC adaptor and provides a variable Digital Pulse Processing Amplifier (0.200 µs to 100 µs peaking time), the MCA function, and all power supplies for the detector. The XR-100CR/PX5 systems ensures stable operation in less than one minute from power turn-on. The resolution for the 5.9 keV peak of 55Fe is 145 eV FWHM to 230 eV FWHM depending on the detector type and shaping time constant (see next page for selection guide).
