Terahertz scale microbunching instability driven by nonevaporable getter coating resistive-wall impedance
Weiwei Li, Tianlong He, Zhenghe Bai
Non-evaporable getter (NEG) coating is widely required in the next generation of light sources and circular colliders for small vacuum pipes to improve the vacuum level, w…
The effect of air exposure on SEY and surface composition of laser treated copper applied in accelerators
Jie Wang, Taaj Sian, Reza Valizadeh +2
In this paper, the effect of air exposure and acetone cleaning on the secondary electron yield (SEY) of laser treated copper were investigated and discussed. The SEY of laser treat…
Numerical Method for Free Electron Laser using an Overmoded Rectangular Waveguide
Weiwei Li, Heting Li, Zhigang He +3
Numerical simulation codes are basic tools for designing Free Electron Lasers (FELs). This paper describes a numerical method for the time-dependent, three-dimensional simulation o…
Generation of coherent two-color pulses at the two adjacent harmonics in a seeded free-electron laser
Zhouyu Zhao, Heting Li, Qika Jia
The growing requirements of pump-probe techniques and nonlinear optics experiments greatly promote the studies of two-color free-electron lasers (FELs). We propose a new method to…
The effect of cavity length detuning on the output characteristics for the middle infrared FEL oscillator of FELiChEM
Zhou-Yu Zhao, He-Ting Li, Qi-Ka Jia
FELiChEM is an infrared free electron laser (FEL) facility under construction, which consists of two oscillators generating middle-infrared and far-infrared laser covering the spec…
The bunch current measurement using high-speed photodetector at HLS II
Tian-Yu Zhou, Yong-Liang Yang, Bao-Gen Sun +7
This contribution presents a novel bunch current measurement system based on an ultra-fast photodetector and a high-speed digitizer at Hefei Light Source II (HLS II). In order to a…
