A high-pressure polarized 3He gas target for nuclear-physics experiments using a polarized photon beam

Solid Polarized Targets for Nuclear and Particle Physics Experiments

The development, in the early 1960s, of the dynamic nuclear polarization process in solid diamagnetic materials, doped with paramagnetic radicals, led to the use of solid polarized targets in numerous nuclear and particle physics experiments. Since then steady progress has been made in all contributing subsystems so that proton polarizations near 100% and deuteron polarizations higher than 50% ...

Spin-polarized 3He : liquid gas equilibrium

We study the effects of nuclear polarization M on the liquid-gas equilibrium phase diagram of 3He, in situations where the saturating vapour pressure increases or decreases as a function of M, and where a metamagnetic instability may occur in the liquid phase. Numerical predictions are given within the frame of a phenomenological model with parameters fitted to reproduce accurately the saturati...

THE SLAC HIGH–DENSITY GASEOUS POLARIZED 3He TARGET*

A large-scale high-pressure gaseous 3He polarized target has been developed for use with a high-intensity polarized electron beam at the Stanford Linear Accelerator Center. This target was used successfully in an experiment to study the spin structure of the neutron. The target provided an areal density of about 7×1021 nuclei/cm2 and operated at 3He polarizations between about 30% and 40% for t...

Polarized 3He Spin Filters for Slow Neutron Physics

Polarized (3)He spin filters are needed for a variety of experiments with slow neutrons. Their demonstrated utility for highly accurate determination of neutron polarization are critical to the next generation of betadecay correlation coefficient measurements. In addition, they are broadband devices that can polarize large area and high divergence neutron beams with little gamma-ray background,...
