A Hydraulic Opposite Anvil System for High-Pressure in-Situ Neutron Diffraction

  • 摘要: 介绍了一套自主研制的用于高压原位中子衍射测量的液压对顶砧系统(HAL-11)。该系统由內压砧、液压加载系统以及对光系统3部分组成。內压腔能兼容不同尺寸以及不同材质的压砧,如碳化钨、蓝宝石、碳化硅、烧结聚晶金刚石等。液压加载系统通过分离式薄型液压千斤顶可提供高达500 kN的加载力,在原位中子散射实验中实时补充由于封垫及样品流变导致的压力下降。对顶砧系统悬挂在四维悬挂式移动平台上,通过两束激光进行对光准直操作,整个系统容易拆卸和组装。使用碳化钨压砧对系统进行压力标定,结果显示,在外加载力为150 kN时,HAL-11系统的样品腔体压力能够达到12 GPa以上。
