Compensation of Earth’s magnetic field at a Double Scattering Mott (DSM) polarimeter



The polarization of a 100 keV electron beam must be measured very precisely by a Double Scattering Mott (DSM) polarimeter For this purpose, a reproducible and stable positioning of the electron beam on the target is required, which is complicated by external varying magnetic fields.


Within this thesis the existing interference along the beam axis is to be measured and a concept for shielding or compensation to be developed.
