Abstract

The SwissFEL Aramis beamline, covering the photon energies between 1.77 keV and 12.7 keV, features a suite of online photon diagnostics tools to help both users and FEL operators in analysing data and optimizing experimental and beamline performance. Scientists will be able to obtain information about the flux, spectrum, position, pulse length, and arrival time jitter versus the experimental laser for every photon pulse, with further information about beam shape and size available through the use of destructive screens. This manuscript is an overview of the diagnostics tools available at SwissFEL and presents their design, working principles and capabilities. It also features new developments like the first implementation of a THz-streaking based temporal diagnostics for a hard X-ray FEL, capable of measuring pulse lengths to 5 fs r.m.s. or better.

摘要

瑞士自由电子激光（SwissFEL）的阿拉米斯光束线覆盖1.77千电子伏特至12.7千电子伏特的光子能量，配备了一套在线光子诊断工具，可帮助用户和自由电子激光操作人员分析数据，并优化实验和光束线性能。科学家能够获取每个光子脉冲的通量、光谱、位置、脉冲长度以及相对于实验激光的到达时间抖动等信息，通过使用破坏性屏幕还可获得有关光束形状和尺寸的更多信息。本文是对瑞士自由电子激光现有诊断工具的概述，介绍了它们的设计、工作原理和功能。它还展示了一些新进展，比如首次为硬X射线自由电子激光实现基于太赫兹条纹的时间诊断，能够将脉冲长度测量至均方根误差为5飞秒或更小。
