通用粉末衍射仪（GPPD）是中国空间中子源（CSNS）上的第一台粉末衍射仪。其目的是为用户提供一种高分辨率、高强度的仪器，用于研究晶体学和磁性结构。在高角度探测器组中，最佳分辨率将优于0.2%。样品位置处的中子通量将在107 n/s/cm 2的量级。2017年11月1日，CSNS开始了加速器、目标站和仪器之间的联合束流调试。首次打开了通用粉末衍射仪（GPPD）的中子束快门。初步测量和标准样品衍射实验的报告，这是用来表征仪器的性能。结果表明，计算结果与设计目标吻合较好。在调试过程中，进行了一系列的用户实验。两个用户的实验结果已经公布。
ABSTRACT The general purpose powder diffractometer (GPPD) is the first powder diffractometer at the China Spallation Neutron Source (CSNS). Its aim is to provide a high-resolution, good-intensity instrument for users to study crystallographic and magnetic structures. The best resolution will be better than 0.2% at high-angle detector bank. The neutron flux at the sample position will be at the order of 107 n/s/cm2. The joint beam commissioning among accelerators, target station and instruments started in the CSNS on November 1, 2017. The neutron beam shutter for the general purpose powder diffractometer (GPPD) was opened for the first time. Initial measurements and standard sample diffraction experiments are reported, which are used to characterize the instrument performance. It is shown that the results agree well with the design goal. During the commissioning, a series of user experiments have been conducted. Two user experimental results have already been published.
