本文讨论了用聚焦离子束从激光加热的金刚石压腔中回收的直径通常为150微米的小样品中制备横截面电子显微镜样品的方法。我们给出了用氦熔化的铁作为压力传递介质到4 Gpa附近的初步观察结果。该项目旨在研究高压和高温下惰性气体在金属和硅酸盐中的捕获机制。
This paper discusses the use of a focused ion beam for the preparation of cross-sectional transmission electron microscopy specimens from small samples, typically 150 micron in diameter, that have been recovered from a laser-heated diamond anvil cell. We present preliminary observations of iron melted with helium as the pressure-transmitting medium to pressures near 4 GPa. The project is designed to investigate entrapment mechanisms of the inert gases in metals and silicates at high pressure and temperatures.
