Laser systems for nuclear photonics at the S-DALINAC* — •Maximilian Meier1, Michaela Arnold1, Vincent Bagnoud2, Joachim Enders1, Norbert Pietralla1, and Markus Roth1 — 1TU Darmstadt, Darmstadt, Deutschland — 2GSI Helmholtzzentrum für Schwerionenforschung, Darmstadt, Deutschland
The superconducting Darmstadt electron linac S-DALINAC is a thrice-recirculating linear accelerator [1] providing electron beams with energies up to 130 MeV and beam currents up to 20 μA for a variety of nuclear physics experiments [2]. It has been operated as Germany*s first energy-recovery linac in the past year [3]. The electron beam is produced either in a thermionic gun or a DC photo-gun using GaAs as cathode material [4]. A new project foresees to use the S-DALINAC for laser Compton backscattering to produce a brilliant monochromatic high-energy photon beam for nuclear photonics applications in photonuclear reactions and for beam diagnostics. An overview over the laser systems at the S-DALINAC will be given, and simulations for the layout of the Compton-backscattering light source will be presented.
