Dp. Barber et al., THE FIRST ACHIEVEMENT OF LONGITUDINAL SPIN POLARIZATION IN A HIGH-ENERGY ELECTRON STORAGE-RING, Physics letters. Section B, 343(1-4), 1995, pp. 436-443
A pair of spin rotators has been installed in the electron ring of HER
A. Longitudinal spin polarizations up to 65% have been reached reprodu
cibly during dedicated measurement time. This is the first time that l
ongitudinal spin polarization has been produced in a high energy elect
ron storage ring.
