高分辨粉末中子衍射仪是我国自主设计、国内加工的中子谱仪,于2009年8月进行了测控系统的调试及检测工作。谱仪的测控软件采用LabWindows/CVI编程语言编写,具有图形化的用户界面(如图1所示),操作简单,灵活易用。通过测控软件可实现单色器台和样品台在0°到360°范围内的转动;探测器台在-10°到70°的转动,不仅可实现第三准直器和3He计数管的离线和在线的安装调试工作,而且利用探测器阵列可完成2θ角度从5°至165°的中子数据收集,转动步距也可在0.01°到0.2°范围内可调。
High resolution powder neutron diffractometer is our own design, domestic processing of neutron spectrometer, in August 2009 conducted a test and control system commissioning and testing. Spectrometer measurement and control software using LabWindows / CVI programming language, with a graphical user interface (Figure 1), easy to operate, flexible and easy to use. Through the measurement and control software, the monochromator and sample stage can be rotated within the range of 0 ° to 360 °. The detector stage rotates from -10 ° to 70 °, which can not only offline the third collimator and the 3He counter And on-line installation and commissioning, and the use of the detector array to complete the 2θ angle from 5 ° to 165 ° neutron data collection, the rotation step can also be adjustable in the range of 0.01 ° to 0.2 °.
