High-Intensity Polarized Ion Sources for the High-Energy Accelerators and Colliders

The latest achievements in the development of polarized proton, negative hydrogen ions H–, D+(D–), and 3He++ sources are presented. The development of new polarization techniques is carried out in BNL, JINR, INR RAS, and other laboratories. Polarized deuteron beams will be required for the polarization program at the NICA collider and in the experiment to search for the electric dipole moment of the proton and the deuteron. Experiments with polarized 3He++ ion beams are part of the experimental program at the NICA collider and the future electron-ion collider (EIC).
