Abstract

The polarization of high-energy electrons can conveniently be measured by means of Møller scattering from polarized electrons in a magnetized ferromagnetic target. This process exhibits in the limit of high energies (E ≥ 100 MeV) still relatively large, energy independent and well known analysator strengths. Furthermore, the laboratory cross section in the kinematical range suitable for polarimeter applications is large
$$ \frac{{d\sigma }}{{d\Omega }}({\Theta _{cm}} = 90^\circ ) = Z \cdot 0.18{\text{ }}barn/sr$$
and energy-independent.
