【摘要】 本文介绍了我国第一台四圆衍射仪的用途、结构和主要性能。这台谱仪是用于分析单晶和磁结构,中子的入射波长固定在1.69×10^-10m,谱仪的能量分辨率为4.7%,在样品位置上的最大中子注量为10⁶n·cm^-2·s^-1,最后与国外同类谱仪的分辨率进行了比较。更多还原

【Abstract】 The first four circle neutron diffractometer in China is introduced. It ismainly used to study the crystal structure and the magnetic structure. Incidentwavelength is fixed at 1.69×10^-10m. The energy resolution of the spectrometer is4.7%. Maximum flux at sample is about 10⁶ n/cm²·s. Finally, the property of thespectrometer is measured and compared with other four circle diffractometer.更多还原
