The core of any spin detector is the spin polarimeter,where the polarization measured. SPECS offers different types of spin polarimeters for use with the PHOIBOS 150 and 225 electron spectrometers. The classical mini Mott detector is based on spin orbit interaction at scattering energies close to 25 keV. The VLEED spin detector is based on exchange interaction at about 6.5 eV scattering energy. The imaging spin detector is based on spin Orbit interaction at energies in the range 10 to 100 eV. The choice of spin polarimeter depends on the requirements on data acquisition speed and whether imaging spin polarimetry is required.
