  • Laser Compton Rückstreu-Quelle am S-DALINAC

    PhD thesis

    A high-power laser system is to be integrated in interaction with the superconducting Darmstadt electron linear accelerator S-DALINAC operated at the Institute of Nuclear Physics of the TU Darmstadt as a source of quasi-monochromatic X-ray radiation based on so-called laser Compton backscattering.

    The aim is to advance the development of LCB sources in the context of linear accelerators with energy recovery and also to establish a possibility for non-destructive beam diagnostics at S-DALINAC for accelerator development and nuclear physics experiments.

  • First setup for cooled GaAs cathodes with increased charge lifetime

    Erster Aufbau einer gekühlten GaAs Kathode mit verbesserter Lebensdauer

    PhD thesis

    Project: Photo-CATCH

    Description:GaAs photocathodes provide a source of highly polarized electron beams. To ensure reliable operation for high current applications it is necessary to increase charge lifetime. To improve the local vacuum condition around the cathode the use of a cryogenic sub-volume is proposed. It is expected that the cryogenic adsorption of reactive residual-gas molecules yield an enhanced lifetime of the negative-electron-affinity surface of the cathode. Additional cooling of the cathode itself allows a higher laser power to be deposited in the material, resulting in higher possible beam currents.

    Implementation and first measurements are planned to be conducted at the TU-Darmstadt Photo-CATCH test set-up to investigate the operational parameters of the new source. Supported in parts by BMBF (05H18RDRB1) and by DFG (RTG 2128 “Accelence”).
