Spectral and temporal observations of csr at anka

ANKA is a synchrotron light source situated at the Karlsruhe Institute of Technology (KIT). Using dedicated low-αc-optics at ANKA we can reduce the bunch length and generate Coherent Synchrotron Radiation (CSR). Studies of the coherent emission in the time domain and spectral measurements in the THz range allow us to gain insight into the longitudinal bunch dynamics. To study interbunch effects we observed THz radiation generated by a single electron bunch either circulating alone in the ring or in a multibunch environment. In this paper we report recent progress in CSR observations using fast THz detectors and a Martin-Puplett spectrometer.
