Self-enhanced coherent harmonic amplification in seeded free-electron lasers
Hanxiang Yang, Jiawei Yan, Haixiao Deng
High-intensity, ultrashort, fully coherent X-ray pulses hold great potential for advancing spectroscopic techniques to unprecedented levels. Here, we propose a novel scheme for gen…
Many-Objective Beam Dynamics Optimization for High-Repetition-Rate XFEL Photoinjector
Zihan Zhu, Jiawei Yan, Duan Gu +1
SHINE, as the first hard x-ray free-electron-laser (FEL) facility in China, is designed to provide high-brightness FEL lasing under high-repetition-rate operation mode. In order to…
First observation of laser-beam interaction in a dipole magnet
Jiawei Yan, Nanshun Huang, Haixiao Deng +3
As a new-generation light source, free-electron lasers (FELs) provide high-brightness X-ray pulses at the angstrom-femtosecond space and time scales. The fundamental physics behind…
Self-Amplification of Coherent Energy Modulation in Seeded Free-Electron Lasers
Jiawei Yan, Zhangfeng Gao, Zheng Qi +23
The spectroscopic techniques for time-resolved fine analysis of matter require coherent X-ray radiation with femtosecond duration and high average brightness. Seeded free-electron…
Multi-beam-energy operation for the continuous-wave x-ray free electron laser
Jiawei Yan, Haixiao Deng
The parallel operation of multiple undulator lines with a wide spectral range is an important way to increase the efficiency of x-ray free electron laser (XFEL) facilities, especia…
Generation of large-bandwidth x-ray free electron laser with Evolutionary Many-Objective Optimization Algorithm
Jiawei Yan, Haixiao Deng
X-ray free-electron lasers (XFELs) are cutting-edge scientific instruments for a wide range of disciplines. Conventionally, the narrow bandwidth is pursued in an XFEL. However, in…
