Amptek recently brought silicon wafer manufacturing in-house and improved the process. The result is a detector with lower noise, lower leakage current, better charge collection, and uniformity from detector to detector. This makes it the best performing Si-PIN detector available.

The XR-100CR is a high performance thermoelectrically cooled Si-PIN X-ray detector and preamplifier. It is typically used in laboratory X-ray spectroscopy applications requiring moderate energy resolution and moderate count rates where cost is important. It is well suited to many XRF applications such as identifying metal alloys, verifying RoHS/WEEE compliance, and detecting lead in paint.

The energy resolution of the XR-100CR ranges from 139 to 190 eV FWHM depending on the detector area. It is best at count rates below 30 kcps and is suited to X-rays between 1.5 and 30 keV.  It uses a fully depleted 500 um Si-PIN photodiode, and is available with 1 or 0.5 mil Be windows.

In the XR-100CR the detector is mounted on an extender (several different lengths are available) with the preamplifier in the attached metal box. It requires a separate signal processor and power supplies; Amptek’s PX5 is recommended and is ideally suited for most laboratory uses. The same Si-PIN detectors are available in the smaller X-123 package or with smaller preamplifiers for OEMs and custom systems.
