ATLAS HPGe Digital MCA

Introduction

        ATLAS is a digital MCA system independently developed by Jiechuang Nuclear Instruments (Beijing) Technology Co., Ltd., concentrated embodiment of the company's comprehensive technical capabilities. It is a desktop low-noise high-performance single/dual-channel 32/64K-channel digital MCA. It integrates signal polarity adjustment unit, fast analog-to-digital conversion (ADC) unit, automatic pole/zero cancellation unit, digital baseline restoration unit, digital pulse shaping unit, and advanced application digital anti-coincidence/anti-cosmic interface unit. It supports almost all types of detectors such as HPGe, NaI, LaBr3, Cd(Zn)Te. The MCA can be directly called and read through GammaSense spectrum acquisition and analysis software with independent intellectual property rights.
