摘要在同步辐射光源下,对高压下物质的研究大多是用单晶金刚石砧的压力室进行的。在某些情况下,这种电池的可用体积(≤ 10−3mm3)会导致问题,特别是在高温和晶体合成时。为了确保压力和温度的充分均匀性,必须使用大样品体积(≥ 1 mm3)的电池。现有的设备进行比较,这种测量与一种新的设置,其中包括一个环形的砧座安排和一个重量轻(50公斤)的新闻与250吨(2.5 MN)的能力。本文报道了该仪器在同步辐射下的初步测试结果。在IUCr研讨会上提出的“高压晶体学的同步辐射仪器”。达雷斯伯里实验室
Abstract Studies of matter under very high pressure at synchrotron radiation sources are mostly done using pressure cells with single-crystal diamond anvils. In some cases the available volume (≤ 10−3mm3)in such cells causes problems especially at high temperature and for crystal synthesis. To ensure sufficient homogeneity of pressure and temperature, the use of cells with large sample volumes (≥ 1 mm3) is necessary. Existing devices for such measurements are compared with a novel setup which consists of a toroidal anvil arrangement and a lightweight (50 kg) press with 250 tonnes (2.5 MN) capacity. Preliminary tests of this instrument with synchrotron radiation are reported. Presented at the IUCr Workshop on ‘Synchrotron Radiation Instrumentation for HighPressure Crystallography’.
