<p class="MsoNormal"><span
style="font-size:12.0pt;font-family:"Times New
Roman",serif">Spin polarization of targets and beams
has been a crucial tool in scattering experiment probes of
nuclear structure. While the properties of the proton have
allowed successful polarized proton targets and beams,
neutrons are more difficult to manipulate in a particle
accelerator beam. Fortunately, other materials, such as 3He,
offer surrogates of the neutron to allow the creation of
“effective” neutron beams to allow the study of neutron in
an accelerator. We are developing a beam source of polarized
3He ions for use at the Relativistic Heavy Ion Collider
(RHIC) at Brookhaven National Lab (BNL), and at the proposed
Electron Ion Collider. This source combines two existing
technologies to create polarized ions which can be injected
into a beamline: the technique of metastability exchange
optical pumping (MEOP) is a decades old process allowing the
polarization of 3He via laser pumping at low pressure in a
small magnetic field; and the electron beam ion source
(EBIS) currently in use at BNL can ionize and extract nearly
any gas for injection into RHIC. A successful polarized 3He
beam which would become a cornerstone of neutron study at
RHIC and at a future electron-ion collider facility.</span><b><i><span
