A Zero-Degree Inline Optical Electron Polarimeter

摘要

We have used a new configuration for a noble gas optical electron polarimeter. This polarimeter is part of an experiment involving dichroic scattering of longitudinally polarized electrons from chiral molecules. Our polarimeter sits along the electron beam axis at the end of the apparatus and measures the polarization of noble gas fluorescence emitted at 0°. The polarimeter is maximally sensitive to longitudinal electron polarization, and it maintains the axial symmetry of our experiment.
