Si-PIN X-ray detectors
 

Si-PIN X-ray detectors

Amptek recently added in-house silicon wafer fabrication and improved the process. The result is a detector with lower noise, lower leakage current, better charge collection, and detector-to-detector uniformity._cc781905- 5cde-3194-bb3b-136bad5cf58d_This makes it the best performing Si-PIN detector available.

 

The Si-PIN is a high performance thermoelectrically cooled X-ray detector and can be combined with various digital pulse processor and preamplifier configurations. Typically used in ray spectroscopy applications XRF laboratories requiring moderate power resolution and moderate count rates where cost is important. Fits well for many XRF applications such as metal alloy identification, RoHS compliance verification /WEEE and the detection of lead in paint.

 

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

 

In the XR-100CR, detector is mounted on an extender (several different lengths available) with preamplifier in attached metal case. Requires separate signal processor and power supplies ; Amptek's PX5 is recommended and is ideal for most laboratory uses. The same Si-PIN detectors are available in the X-123 package more small or with smaller preamps for OEM and custom systems.
 
 

 

El  X-123  is a complete X-ray detector system in a small handheld box. X-1234 represents the culmination of years of developing X-ray detectors at Amptek. Our philosophy has always been to create small, low-power, high-performance instruments while keeping their operation simple. El X -123 exemplifies this philosophy by providing in a single package the XR-100CR X-ray detector and its charge-sensitive preamplifier; the DP5 digital pulse processor with pulse shaper, MCA, and interface;  and the PC5 power supply. All that is needed is a +5 V DC input and a USB or RS-232 connection to your computer._cc781905- 5cde-3194-bb3b-136bad5cf58d_
