Abstract

The VISA (Visible to Infrared SASE Amplifier) project is designed to be a SASE-FEL driven to saturation in the sub-micron wavelength region. Its goal is to test various aspects of the existing theory of self-amplified spontaneous emission, as well as numerical codes. Measurements include: angular and spectral distribution of the FEL light at the exit and inside of the undulator; electron beam micro-bunching using CTR; single-shot time resolved measurements of the pulse profile, using an auto-correlation technique and FROG algorithm. The diagnostics are designed to provide maximum information on the physics of the SASE-FEL process, to ensure a close comparison of the experimental results with theory and simulations.

VISA FEL的光子束诊断

VISA(可见到红外SASE放大器)项目被设计成一个SASE- fel驱动到亚微米波长区域的饱和。其目的是测试现有的自放大自发发射理论的各个方面，以及数字编码。测量结果包括:在波动器出口和内部的FEL光的角分布和光谱分布;CTR电子束微聚束;使用自相关技术和FROG算法对脉冲剖面进行单次时间分辨测量。诊断的目的是提供关于SASE-FEL过程的最大物理信息，以确保实验结果与理论和模拟的密切比较。
