In the upcoming Jülich Electric Dipole moment Investigations (JEDI) project, the essential point would be to measure tiny beam polarization change over a long period. The particle scarcity in the polarized deuteron or proton beams and its slow extraction rate puts very difficult experimental limitations on the polarimetry. At present, the EDDA detector (build with plastic scintillators) is...

The low energy polarimeter (LEP [1]) is a polarimeter in the injector of the Cooler Synchrotron (COSY [2]). COSY is a facility for cooled polarized beams at the Forschungszentrum in Jülich. The beam polarization is measured using scattering off carbon and polyethylene (CH2) targets. Up to now only elastic scattering off the carbon atoms is used for polarimetry. The outgoing particles are...

Modern electron scattering experiments, and in particular those utilizing
parity-violating electron scattering, require precise knowledge of electron beam
polarization. Recently at Jefferson Lab Hall C, sub-percent beam polarization
determination was achieved during the Q-weak experiment using two independent
polarimeters. The Hall C Moller uses a pure iron foil that is driven...
