Abstract

We discuss ion extraction from an internal target in a storage ring, separation of atomic and molecular species, and subsequent measurement of the polarization of the atomic ions. This technique can be applied to internal targets of polarized hydrogen, deuterium, ³He and other gases. Here, we report on the development of such a device for a tensor polarized deuterium gas target internal to a medium-energy electron storage ring. Ions were extracted from a storage cell using a spherical deflector and transported to a mass analyzer. In a prototype setup, using electrons from a gun to simulate the electron beam from a storage ring, the tensor polarization of the atomic ions was measured using the ³H(d^→, n) α reaction. The data show that the extraction of ions from a storage-cell target, followed by their mass and polarization analysis, allows the determination of the nuclear polarization of the target independent of its spatial and temporal variations.
