In this article, the specification and application of the new double-sided YAG laser-heating system built on beamline I15 at Diamond Light Source are presented. This system, combined with diamond anvil cell and X-ray diffraction techniques, allows in situ and ex situ characterization of material properties at extremes of pressure and temperature. In order to demonstrate the reliability and stability of this experimental setup over a wide range of pressure and temperature, a case study was performed and the phase diagram of lead was investigated up to 80 GPa and 3300 K. The obtained results agree with previously published experimental and theoretical data, underlining the quality and reliability of the installed setup.
本文介绍了基于钻石光源（Diamond Light Source）I15光束线构建的新型双面YAG激光加热系统的规格和应用。该系统与金刚石对顶砧和X射线衍射技术相结合，能够在极端压力和温度条件下对材料特性进行原位和非原位表征。为了证明该实验装置在广泛的压力和温度范围内的可靠性和稳定性，进行了一个案例研究，并对铅的相图进行了研究，压力高达80 GPa，温度高达3300 K。所得结果与先前发表的实验和理论数据一致，突出了所安装装置的质量和可靠性。
