Characterization of a dispersion free bending magnet of the S-DALINAC Polarized-electron Injector* — •René Heber, Maximilian Herbert, Joachim Enders, Yuliya Fritzsche, and Vincent Wende — Institut für Kernphysik, Technische Universität Darmstadt, Schlossgartenstraße 9, 64289 Darmstadt

The S-DALINAC Polarized-electron Injector SPIn creates polarized electron beams of 100 keV. An upgrade is planned to increase the electron energy to 200 keV. A dispersion-free bending magnet, a so-called alpha-magnet, is currently used to transfer the electron beam from the vertical to the horizontal beamline. Subject of this contribution are measurements to determine if the magnet can be used to transfer 200 keV electron beams. Therefore the magnetic field of the alpha-magnet, the temperature of the magnet coil, and the trajectory of the electron beam are observed and simulated [1].
