A polarized 3He beam in RHIC would enable new, unique, high energy QCD studies of neutron structure with existing polarized proton beams. In addition, it could be used for important tests of the Standard Model in a future electronion collider. A source of polarized 3He++ ions utilizing the new Electron Beam Ionization Source (EBIS) at BNL is under development. 3He atoms can be polarized using metastability exchange optical pumping (MEOP) and the atoms transferred to EBIS. Fully stripped 3He++ ions would be extracted from EBIS and their polarization measured at low energies. The concept for the ion source is presented and the plan for the development described.
