A double-sided laser heating setup for diamond anvil cells installed on the ID24 beamline of the ESRF is presented here. The setup geometry is specially adopted for the needs of energy-dispersive X-ray absorption spectroscopic (XAS) studies of materials under extreme pressure and temperature conditions. We illustrate the performance of the facility with a study on metallic nickel at 60 GPa. The XAS data provide the temperature of the melting onset and quantitative information on the structural parameters of the first coordination shell in the hot solid up to melting.
本文介绍了一种安装在欧洲同步辐射装置（ESRF）ID24光束线上的用于金刚石对顶砧的双面激光加热装置。该装置的几何结构是专门为在极端压力和温度条件下对材料进行能量色散X射线吸收光谱（XAS）研究的需求而设计的。我们通过对60吉帕压力下金属镍的研究来说明该装置的性能。XAS数据提供了熔化起始温度以及关于热固态直至熔化时第一配位层结构参数的定量信息。
