THz-Based Longitudinal Beam Diagnostics at DELTA — •Raffael Niemczyk, Fin Hendrik Bahnsen, Max Bolsinger, Fabian Götz, Svenja Hilbrich, Markus Höner, Marc Andre Jebramcik, Shaukat Khan, Nils Lockmann, Carsten Mai, Arne Meyer auf der Heide, Robert Molo, Gholamreza Shayeganrad, Peter Ungelenk, and Dennis Zimermann — Center for Synchrotron Radiation (DELTA), TU Dortmund University, Dortmund, Germany

At the 1.5-GeV electron storage ring DELTA operated by the TU Dortmund University, THz radiation is induced by a laser-electron interaction in an undulator. A dip in the longitudinal charge distribution forms after the electron bunch passes dispersive magnet structures leading to the emission of coherent THz radiation. Next to turn-by-turn-resolved studies of the THz intensity, a set-up for electro-optical measurements of the THz field is being commissioned. This method will allow to analyze the charge distribution on a sub-ps scale.
