NONDESTRUCTIVE BUNCH LENGTH MEASUREMENT WITH COHERENT DIFFRACTION RADIATION

摘要

This paper presents the observation and use of coherent diffraction radiation generated by a 26 MeV beam of femtosecond electron bunches at the SUNSHINE (Stanford UNiversity Short INtense Electron source). The radiation is used to measure the bunch length in an autocorrelation technique. This bunch length measurement using coherent diffraction radiation has the great advantage of being nondestructive. Data analysis and limitations of the technique will be discussed.
