Design of a Laser Compton Backscattering Source for Beam Diagnostics at the S-DALINAC* — •Maximilian Meier1, Michaela Arnold1, Vincent Bagnoud2, Joachim Enders1, Norbert Pietralla1 und Markus Roth1 — 1IKP, TU Darmstadt, Germany — 2GSI, Darmstadt, Germany
Laser Compton Backscattering (LCB [1]) provides quasi-monochromatic highly polarized beams on the X-ray and gamma-ray regime for a variety of applications. A powerful stable and well synchronized laser with a high repetition rate is essential for a high-flux Compton light source. A project at TU Darmstadt foresees to synchronize a high-repetition high-power laser with electrons from the Superconducting DArmstadt electron LINear ACcelerator (S-DALINAC [2]) to realize a LCB photon beam with energy up to 180 keV. The main goal in the first years will be to use LCB as an additional diagnostic tool for determining the electron beam energy and the energy spread of the S-DALINAC, with respect to the energy-recovery linac (ERL [3]) operation as well as the optimizing design considerations for a Compton light source. An overview over the design concept of the LCB Source at the S-DALINAC will be given, simulations on the layout and the estimated output will be presented.
