摘要

摘要: 作为中国散裂中子源(CSNS)工程中多功能反射(RM)谱仪一部分的³He管探测器数据获取系统不仅要具有基本的读取和处理数据的功能，还需要协调配合谱仪的整体运行，稳定可靠地与其它异构系统进行交互。通过规划数据获取的整体框架，采取有效的方式优化关键部分，另外挑选合适的三方软件包整合到数据获取系统中，达到了该系统操作方便灵活、功能完善、运行稳定可靠并且高效率，满足谱仪实验需求的目的。包括数据获取系统在内的多功能反射谱仪顺利通过了国家验收，目前这套数据获取系统已经成功应用在多功能反射谱仪的束流实验中。

Abstract: As a part of the reflectometer in China Spallation Neutron Source (CSNS), data acquisition system (DAQ) of ³He tubes detector should not only have basic functions of data readout and processing, but also coordinate the whole operation of spectrometer and interact with other heterogeneous systems stably and reliably. By planning the whole frame, adopting effective methods, optimizing the key components of DAQ system, choosing and integrating appropriate third-party software, DAQ system achieves goals of convenient and flexible operation, having complete functions and running stably, reliably and efficiently. It meets the demands of the reflectometer. The reflectometer with the DAQ has passed national acceptance. By now, this DAQ system has been applied in neutron beam tests on the reflectometer successfully.
