在中子衍射谱仪样品的原位高温加载实验中,需要用到高温炉装置。现有的用于中子衍射的高温炉装置为整体封闭式结构,其主要缺点是中子需穿透炉体壁到达样品,衍射中子束再次穿过炉壁到达探测器,由于炉体壁对中子的吸收造成束流强度减弱,不利于高计数率的实验测量。针对封闭 In the neutron diffraction spectrometer samples in-situ high-temperature loading experiments, the need to use high-temperature furnace device. The existing high-temperature furnace for neutron diffraction device is a closed structure, the main disadvantage is that neutrons need to penetrate the furnace wall to reach the sample diffraction neutron beam again through the furnace wall to reach the detector, the furnace wall Absorption of neutron beam intensity decreases, is not conducive to high count rate of experimental measurements. For closed
