| Popis: |
The paper describes the commissioning of the experimental equipment and the machine studies required for the first spin-filtering experiment with protons at a beam kinetic energy of 49.3 MeV in COSY. The implementation of a low-β insertion made it possible to achieve beam lifetimes of τ_{b}=8000 s in the presence of a dense polarized hydrogen storage-cell target of areal density d_{t}=(5.5±0.2)×10^{13} atoms/cm^{2}. The developed techniques can be directly applied to antiproton machines and allow the determination of the spin-dependent p[over ¯]p cross sections via spin filtering. |
