Influence of RF Phase Modulation on Laser-Induced Coherent Synchrotron Radiation — •Marc Andre Jebramcik, Fin Hendrik Bahnsen, Max Bolsinger, Svenja Hilbrich, Shaukat Khan, Carsten Mai, Arne Meyer auf der Heide, Robert Molo, Gholamreza Shayeganrad, and Peter Ungelenk — Center for Synchrotron Radiation (DELTA), TU Dortmund University, Dortmund, Germany

In circular accelerators, RF phase modulation is routinely used to prolong the beam lifetime and to damp multi-bunch instabilities. At the 1.5-GeV synchrotron light source DELTA operated by the TU Dortmund University, synchronized RF phase modulation has also been used to increase the intensity of the ultrashort coherent pulses in the VUV and THz regime generated by the coherent harmonic generation (CHG) technique since 2014. The quality of the laser-electron interaction is heavily influenced by the energy spread and density of the electron bunches. Hence, RF phase modulation can be used to modulate these parameters in order to achieve an increased intensity of the laser-induced radiation. An analysis regarding the relationship between synchronized RF phase modulation and the laser-induced radiation is presented.
