PSICHE（Pressure，Structure and Imaging by Contrast at High Energy）是SOLEIL同步加速器的高能光束线。该光束线旨在利用衍射在极压下研究样本，并为材料科学和其他不同应用进行成像和断层扫描。本文介绍了断层摄影机和使用的束线成像，重点是相对于现有的仪器的发展。特别值得一提的是具有自由中心孔径的高负载能力旋转平台，用于安装大型或复杂样品和样品环境，用于粉红光束成像的X射线镜和滤光片，以及用于组合成像和衍射测量的多种选项。我们描述了如何将X射线成像技术集成到高压实验中。光束线的设计和规格进行了说明，并从第一个用户实验得出的几个案例研究。出版社：AIP Publishing
PSICHE (Pressure, Structure and Imaging by Contrast at High Energy) is the high-energy beam line of the SOLEIL synchrotron. The beam line is designed to study samples at extreme pressures, using diffraction, and to perform imaging and tomography for materials science and other diverse applications. This paper presents the tomograph and the use of the beam line for imaging, with emphasis on developments made with respect to existing instruments. Of particular note are the high load capacity rotation stage with free central aperture for installing large or complex samples and sample environments, x-ray mirror and filter optics for pink beam imaging, and multiple options for combining imaging and diffraction measurement. We describe how x-ray imaging techniques have been integrated into high-pressure experiments. The design and the specifications of the beam line are described, and several case studies drawn from the first user experiments are presented. Published by AIP Publishing.
