Converter of orbital momentum into spin momentum for the polarization of particle beams |
摘要 |
<p>Apparatus for spin polarizing a particle beam, which is adapted to process an input particle beam (Bi) in such a way as to generate an at least partially spin polarized output particle beam (Bo), and comprises:
- a vortex beam generator (1) for imparting orbital angular momentum to the input particle beam;
- an electromagnetic field generator (5) for generating a transverse magnetic field, space-variant and symmetric with respect to the (z) axis of the input particle beam, in such a way as to change the spin of the particles and attach thereto a plurality of different values of orbital angular momentum in dependence on their input spin values; and
- a beam component separating group (7, 9) for spatially separating the particles in dependence on their orbital angular momentum values, in such a way as to obtain the at least partially spin polarized output particle beam.</p> |
