AI Technical Summary

Technical Problem

In neutron scattering experiments, conventional glues or adhesives introduce high-intensity background noise, which interferes with the true scattering signal of the sample, reduces the accuracy of the test, and the sample fixation process is cumbersome, inefficient and risky.

Method used

The encapsulation device, which employs a base, clips, and compression structure, uses axial pressure and wire holes to secure the sample by binding the clips with fixing wires, eliminating the need for glue. It also features a switchable connection method between the cap and the connecting rod, simplifying sample assembly and transfer.

Benefits of technology

Reduce background interference, preserve the true scattering signal, improve the signal-to-noise ratio and experimental accuracy, simplify the operation process, reduce the risk of sample damage, and improve experimental efficiency.

Abstract

本发明公开了一种中子散射样品的封装装置及固定组件,属于中子散射实验设备技术领域。其中,封装装置包括基座、两个夹片和压紧结构,基座内部设有容纳槽,基座的周壁设有至少两个第二开口;两个夹片能够通过第一开口沿容纳槽的深度方向依次放置于容纳槽内,并将样品夹持于两个夹片之间,每个夹片设有多个穿线孔;压紧结构连接于基座,压紧结构能够向两个夹片施加沿第一开口朝向容纳槽底壁的压力;其中,当两个夹片位于容纳槽内时,每个第二开口能够显露出每个夹片的至少一个穿线孔,以供固定丝线分别穿过两个夹片的穿线孔,并限制两个夹片的相对位移。本发明降低了背景干扰,保留了样品的真实散射信号,还确保了封装结构的整体性和结构稳定性。
