A variable energy Möller polarimeter at the S-DALINAC* — •Roman Barday1, Joachim Enders1, Wolfgang Müller2, and Bastian Steiner2 — 1Institut für Kernphysik, TU Darmstadt — 2Institut für Theorie Elektromagnetischer Felder, TU Darmstadt
A coincidence Möller polarimeter is designed for both cw and pulsed beam of the Superconducting Darmstadt Linear Accelerator S-DALINAC where polarized electron beams will become available in 2008. The designed polarimeter covers an energy region between 15 and 130 MeV. The beam polarisation at currents of up to 1 µA is inferred from measurement of the asymmetry in polarized electron-electron scattering from the Fe-Co foil. The influence of the atomic motion of the target electrons on the polarisation, the so-called Levchuk effect was investigated.
