The extraction beam guide of the S-DALINAC contains the high-energy scraper system. This has various slot systems that can be used to define the beam energy or to reduce the beam halo / background. The main slits – used for energy definition – have a current measurement. Via current changes on the two jaws of this system, an energy change of the beam can be detected with very fine resolution according to the very high dispersion set there. The extent to which energy changes can be transported from the accelerator hall to the extraction beamline depends on the beam dynamics set.

Within the scope of this master thesis, the current measurement on the energy-defining scraper system for stabilizing the beam energy will be set up and put into operation. Beam dynamics simulations and measurements will be used to investigate the differences between the different operating modes with the respective beam dynamics and their effects on the stabilization.
