Abstract :
The new NdFe polarimeter aims at photon, electron and positron polarimetry at energies up to 200 MeV. Spin dependent Compton, Moller or Bhabha scattering in magnetised NdFe layers can be recognised by means of position sensitive silicon sensors. Theoretical studies showed that the figure of merit of this polarimeter is much better compared to that of others. Tests of the silicon vertex detection system have shown satisfactory results. The polarimeter will be described and results of the longitudinal polarisation measurements of electrons will be presented
