Topaz HR Multi-Channel Analyzer

Introduction Introduced March 2018, Topaz-HR is a compact stand-alone MCA for high-resolution detectors such as Hyper Pure Germanium Detectors (HP-Ge). Topaz-HR is a compact, stand-alone digital Multi-Channel Analyzer (MCA), which is able to perform a Pulse Height Analysis (PHA) of the signal produced by high resolution gamma-ray semiconductor detectors, such as Hyper-Pure Germanium Detectors (HPGe). These detectors are commonly used in high-resolution gamma-ray spectrometry, an analysis method extensively used by advanced radio-analytical laboratories as part of comprehensive nuclear analytical methods. The Topaz-HR MCA can also be used with detectors with lesser energy resolution, such as scintillators like NaI (Tl), LaBr3, CeBr3, etc. The Topaz-HR is supplied with a basic software package that allows the user to control the device, and to acquire and visualize the energy spectrum. The software incorporates an advanced and easy-to-use “discovery” function that can be used to detect
