本成果介绍了欧洲XFEL用于束流能量监测的方法，该方法基于束流位置监测器数据对加速器晶格在线模型进行高性能轨迹拟合。与大多数其他方法不同，它可应用于晶格中具有足够色散的几乎任何区段，无需手动调整。我们的实现足够快速，可在与其他进程共享的常规x86硬件上实时每秒测量数千个束团的能量。本文给出了该技术的简要概述，并利用加速器数据进行了说明。
英文摘要
This contribution presents the method used for beam energy monitoring at the European XFEL. It relies on high-performance trajectory fitting of beam position monitor data against an online model of the accelerator lattice. Unlike most other methods, it can be applied to virtually any section of the lattice with sufficient dispersion without the need for manual adaptation. Our implementation is fast enough to measure the energy of many thousands of bunches per second in realtime on conventional x86 hardware shared with other processes. A short outline of the technique is presented and illustrated with data from the accelerator.
