位于汉堡的DESY的欧洲X射线自由电子激光器（XFEL）[1]将在未来几年内开始运行，从而带来新的突破性研究机会。整个系统需要非常精确的时钟和触发分配，与1.3 GHz系统RF频率同步，距离超过3.4 km。新的实验需要其他商业解决方案无法提供的功能。斯德哥尔摩大学和DESY的研究人员开发了XFEL计时系统的原型。XFEL将使用先进的ATCA和Micro-TCA系统，因为它们具有先进的功能和可靠性。该计时系统已适应Micro-TCA总线标准，并遵循即将推出的新xTCA物理标准。原型是功能齐全和完整的。它将作为整个计时系统未来发展的平台。本文介绍了硬件设计和一些测试结果使用的原型板。
The European X-ray Free Electron Laser (XFEL) [1] at DESY in Hamburg will begin operating in the next few years, enabling new, ground-breaking research opportunities. The entire system requires very precise clock and trigger distribution, synchronous with the 1.3 GHz system RF-frequency, over distances of more than 3.4 km. The new experiment demanded features that other commercial solutions could not yet provide. Researchers at Stockholm University and DESY have developed a prototype for the timing system of XFEL. It has been decided that XFEL will use modern ATCA and Micro-TCA systems because of their advanced features and reliability. The timing system has been adapted to the Micro-TCA bus standard and also follows the new upcoming xTCA for physics standard. The prototype is fully functional and complete. It will serve as a platform for future development of the whole timing system. This paper describes the hardware design and some test results using the prototype board.
