It has been realized for some time that the use of the charge exchange reaction of negative deuterium ions with polarized neutral hydrogen yielding neutral deuterium and polarized negative hydrogen ions to produce polarized H/sup -/ ions could be very efficient. While intense H/sup -//D/sup -/ ion sources exist, one encounters space charge problems when trying to put this scheme into practice. In this paper, a simple method, which uses a self-extracted D/sup -/ beam from a ring magnetron source, is proposed. The basic idea is presented, approximate numbers are given and the expected intensity is estimated. The method not only offers improvement in intensity, but equally important, improvements in reliability and lifetime.
