Abstract

The X-ray Pump-Probe instrument achieves femtosecond time-resolution with hard X-ray methods using a free-electron laser source. It covers a photon energy range of 4-24 keV. A femtosecond optical laser system is available across a broad spectrum of wavelengths for generating transient states of matter. The instrument is designed to emphasize versatility and the scientific goals encompass ultrafast physical, chemical and biological processes involved in the transformation of matter and transfer of energy at the atomic scale.

摘要

X射线泵浦-探测仪利用自由电子激光源,通过硬X射线方法实现了飞秒时间分辨率。它覆盖4-24 keV的光子能量范围。一个飞秒光学激光系统可在广泛的波长范围内使用,用于产生物质的瞬态。该仪器的设计强调多功能性,其科学目标包括在原子尺度上物质转化和能量转移过程中涉及的超快物理、化学和生物过程。
