Abstract
Accumulation of protons and polarized protons by photo-ionization injection are described. This method consists of (l) producing the neutral hydrogen beam by Lorentz stripping, (2) excitation of the neutral hydrogen beam with a laser, and (3) ionization of the hydrogen beam in the 2P excited state with another laser. When the laser for the excitation is circularly polarized, we can get a polarized proton beam. An ionization efficiency of 98% and a polarization of 80% can be expected by an intense laser beam from a FEL (Free Electron Laser).
