DELTA is a 1.5-GeV electron storage ring operated by the Center for Synchrotron Radiation at TU Dortmund University. Following a laser-electron interaction in an electromagnetic undulator, a sub-picosecond modulation of the electron density leads to coherent ultrashort THz pulses, which are extracted by a dedicated THz beamline. Studies of the turn-by-turn evolution of the density modulation and the spectrum of the THz pulses have been continued experimentally and with simulations. For diagnostic purposes a set-up consisting of a spectrometer and different types of ultrafast detectors was used in cooperation with KIT in Karlsruhe.
