Abstract

NSF using gaseous polarized ³He became a popular tool for many polarized neutron scattering applications due to the number of advantages that this technique presents, but also due to significant increasing of technical performancies demonstrated in that field in the last years. The realization of flexible and reliable devices for neutron beam polarization is a focal point in the instrumental development program at the Hahn-Meitner Institute Berlin (HMI). The technique applied in our case to obtain nuclear-spin-polarized ³He is metastability-exchange optical pumping (MEOP) using a cw Nd:LNA laser with 5.8 W output power and 2.5 GHz bandwidth. The general aspects regarding optical pumping in optical polarizing cells are described. The construction of the optical pumping volume is presented, the last results regarding optical pumping cells (OPC) and filter cells preparation are discussed. The status and perspectives of the project are presented.
