European X-ray Free Electron Laser (Eu-XFEL) is a high repetition rate free electron laser based on a superconducting linear accelerator. Since the start of user delivery, it has greatly promoted the development of X-rays in many fields such as biology, chemistry, and condensed matter physics. The three beam lines of the Eu-XFEL cover the X-ray photon energy from 300eV to 30keV. In recent years, hard x-ray self-seeding, two-color X-rays and high-power ultrafast X-rays have been investigated. Such advanced operating modes have greatly improved the application level of the free electron lasers. In this report, I will introduce the latest progress and user delivery of these new operating modes.

基于超导直线加速器的高重频欧洲自由电子激光European XFEL自2017年开始为用户供光以来，极大的推动和促进了X射线在生物、化学和凝聚态物理等多个领域的发展。欧洲自由电子激光的三条束线覆盖了从300eV到30keV的X射线能谱，近年来又加入了硬射线自种子(hard x-ray self-seeding)，双色X射线(two color)及高功率超快XFEL脉冲等先进运行模式，更大程度提高了自由电子激光的应用层面。在这个报告中，我将介绍这些新型运行模式的最新工作进展及供光情况。
