Smith-Purcell radiation from a charge moving above a finite-length grating with rectangular profiles
Weiwei Li, Weihao Liu, Zhigang He +2
Smith-Purcell radiation is generated by a charged particle beam passing close to the surface of a diffraction grating which has a strong dependency of the emitted radiation intensi…
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…
Velocity bunching in travelling wave accelerator with low acceleration gradient
Rui-Xuan Huang, Zhi-Gang He, Wei-Wei Li +1
We present the analytical and simulated results concerning the influences of the acceleration gradient in the velocity bunching process, which is a bunch compression scheme that us…
Compact narrow-band THz radiation source based on photocathode rf gun
Li Wei-Wei, He Zhi-Gang, Jia Qi-Ka
Narrow-band THz coherent Cherenkov radiation can be driven by a subpicosecond electron bunch traveling along the axis of a hollow cylindrical dielectric-lined waveguide. We present…
Generation and measurement of sub-picosecond electron bunch in photocathode rf gun
Weiwei Li, Zhiagng He, Qika Jia
We consider a scheme to generate sub-picosecond electron bunch in the photocathode rf gun by improving the acceleration gradient in the gun, suitably tuning the bunch charge, the l…
