For the application of neutron scattering spectrometer and the protection of reactor radiation, a neutron monochromator shielding assembly with continuously variable take-off angle was designed and fabricated, using a special electromagnetic localizer and computer automatization technique. The take-off angle is able to change from 40° to 110° owing to the special rotating system. Meanwhile, the radiation around the monochromator is shielded, and the experimental background and radiation damage to people is decreased.

从反应堆辐射防护和中子散射谱仪应用角度出发，利用电磁铁定位技术和计算机自动化控制技术，设计加工了一种起飞角连续可变的中子单色器屏蔽装置。该装置通过特定的转动流程，实现了起飞角在40°~110°范围内连续可变，同时满足了单色器周围的辐射屏蔽要求，降低了实验本底和对人体的辐射伤害。
