Description

Polarized He-3 is accepted as an effective polarized neutron for scattering experiments to study hadron structure. The HERMES experiment was commissioned and took first data in 1995 running with a polarized He-3 target. Targets have been in routine use at Jefferson Lab, Mainz and other laboratories. The MIT group has pioneered development of high field optical pumping of He-3 gas for both a polarized ion source for EIC at BNL and polarized target development at CLAS12 at Jefferson Lab.
The status of developments and planned physics will be described.
