Design and Status of the Laser-Compton Backscattering Source at the S-DALINAC* — •Maximilian Meier, Michaela Arnold, Joachim Enders, and Norbert Pietralla — Technische Universität Darmstadt, Fachbereich Physik, Institut für Kernphysik, Darmstadt, Germany

Laser-Compton Backscattering (LCB) provides quasi-monochromatic highly polarized beams in the X-ray and gamma-ray regimes for a variety of applications. A powerful, stable, and well synchronized laser with a high repetition rate is essential for a high-flux Laser-Compton light source with narrow energy-bandwidth. This contribution presents the design of an LCB-based X-ray source at the Superconducting DArmstadt electron LINear ACcelerator (S-DALINAC), aimed at identifying optimum conditions for LCB photon sources for nuclear-photonics applications and accelerator science. At the LCB source a highly repetitive high-power laser beam will be scattered off the electron beam of the S-DALINAC. As a first step, the X-rays from LCB will be used as a diagnostic tool for determining the electron beam energy and the energy spread of the S-DALINAC. Later, combining LCB with the S-DALINAC’s operation as an Energy Recovery Linac (ERL), is expected to yield X-rays at several 10s of keV with high brilliance.
