Polarized Ion Sources with a Storage Cell in a Charge-Exchange Plasma Ionizer
摘要
Sources of polarized protons and deuterons with a storage cell for polarized atoms in a charge-exchange plasma ionizer are considered. A new approach is based on the transverse injection of an atomic beam into a T-shaped storage ionizer cell. This scheme has a number of advantages over sources with the longitudinal injection of the atomic beam into the storage cell, which will help eliminate the limitations inherent in a source with longitudinal injection and significantly reduce the emittance of the polarized ion beam. This should increase the intensity and polarization of the proton and deuteron beams from the source, which is required for obtaining the design luminosity and polarization at the Nuclotron based ion collider facility (NICA, Joint Institute for Nuclear Research).
