Amptek X 123 CdTe

The X-123CdTe is a complete X-Ray & Gamma-Ray Detector System in one small box that fits in your hand. Amptek's specialty is X-ray and gamma-ray spectrometers, which are small, low power, high performance, and simple to operate. The X-123CdTe combines in a single package Amptek's standard, high performance X-ray spectroscopy components: the XR100T-CdTe detector and preamplifier, DP5 digital pulse processor and MCA, and PC5 power supply. The result is a complete integrated system which can fit in your hand. In many commercially available systems, the preamplifier alone has more size, mass, and power than this integrated system. It requires only 2 connections to run: +5 VDC power and a standard RS-232 or USB bus. With the X-123CdTe, anyone can rapidly obtain high quality X-ray and gamma-ray spectra.
