A Potential Method for Diagnostics of Subfemtosecond Electron Beams Using Coherent Optical Transition Radiation

摘要

Coherent transition radiation (CTR) is widely used in determining the longitudinal e-beam dimensions in the accelerator technology applications. In this study, the CTR process is investigated in a real Au-target for the sake of measuring the size characteristics of the electron bunches with lengths from 100 to 300 nm, and possible applications of such targets is demonstrated.
