Summary
Successful experiments with proton beams of energies in the range of a few GeV have been performed since 1950s while the first polarized proton beam was accelerated at Zero Gradient Synchrotron operated between 1964 and 1979 [1]. Except for the effortful spin filtering [2, 3], no method for the production of a well-defined polarized antiproton beam with high intensity is available. Some of proposed solutions were already discarded due to expected low-beam intensities or low degree of polarization. Lack of experimental data (especially the spin-dependent part of the total antiproton–proton scattering cross section) makes it impossible even to estimate the expected efficiency of the proposed method [4]. The goal of the P349 experiment is to test whether the production process can be itself a source of antiproton polarization [5, 6]
