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.
PSICHE（高能下的压力、结构与对比成像）是索莱伊同步加速器的高能束线。该束线旨在利用衍射在极端压力下研究样品，并为材料科学及其他各种应用进行成像和断层扫描。本文介绍了断层扫描仪以及该束线在成像方面的应用，重点阐述了相对于现有仪器所取得的进展。特别值得一提的是具有自由中心孔径的高负载能力旋转台，用于安装大型或复杂样品及样品环境；用于粉红光束成像的X射线镜和滤光光学器件；以及用于结合成像和衍射测量的多种选项。我们描述了X射线成像技术是如何被整合到高压实验中的。介绍了束线的设计和规格，并展示了首批用户实验中的几个案例研究。
