高分辨粉末中子衍射仪是中子散射工程首批在建谱仪之一。2009年高分辨粉末中子衍射仪主要进展有下面的这些。1单色器屏蔽体的设计加工粉末衍射仪单色器屏蔽体的设计充分考虑了屏蔽效果和谱仪的空间布局,采用积木式分块结构和阶梯状搭建方式,并为高强度衍射仪预留了两个出射孔。根据中国先进研究堆(CARR)的现场情况,采取了预先加工和现场浇注结合的方式。2009年12月,单色器屏蔽体完成了原地验收,预计2010年1月进行现场验收和搭建。
High-resolution neutron powder diffraction neutron scattering project is one of the first in the spectrometer. The main progresses of high resolution neutron powder diffractometer in 2009 are as follows. 1 monochromator shield design and processing Design of monochromator shielding powder diffractometer full consideration of the shielding effect and the spatial layout of the spectrometer, the use of building block structure and ladder-like structure, and high-intensity diffractometer Left two exit holes. According to the scene of China Advanced Research Reactor (CARR), a combination of pre-processing and on-site pouring was adopted. In December 2009, the monochromator shield completed its in-situ acceptance and is expected to be field-accepted and erected in January 2010.
