Abstract

Coherent Synchrotron Radiation (CSR) has been proven to be a powerful spectroscopic source in the THz range at electron storage rings. However, CSR driven instabilities in the electron distribution within the bunch can cause fluctuations in the emitted THz radiation heavily disturbing the quality of Fourier transformed spectra. Here we discuss the interference of the coherent radiation emitted by two successive electron bunches as a possible tool for studying the longitudinal bunch coherence.
