A dual-optically-pumped polarized negative deuterium ion source

摘要

Acceleration of polarized deuterons in the KEK 12-GeV proton synchrotron is under discussion. To get a highly vector polarized deuteron beam, a new type of optically pumped polarized ion source (OPPIS) with dual optical pumping has been developed. In the preliminary experiment, we found that the dual-pumped polarized scheme had a large potential to generate highly nuclear-spin polarized negative deuterium ions.
