The ability to optically-pump Helium-3 provides the opportunity to create a convenient approximation of a polarized neutron target since to a high degree, the polarization of the 3He arises solely due to the neutron. The advent of high-density, high-polarization 3He targets opens up many possibilities in the study of the spin structure of nucleons and nuclei.
In this laboratory we produce 'Helium-3 glass cells' that are primarily used as targets for the accelarator at Jefferson Lab in Newport News, VA, but also for other accelarators like TUNL in Durham, NC.
Our collaboration studies the substructure of neutrons in electron scattering experiments at JLab.
The main mission of Jefferson Lab is nuclear physics research in the Continuous Electron Beam Accelerator Facility (CEBAF). CEBAF, based on super-conducting radio-frequency (SRF) accelerating technology, is the world's most advanced particle accelerator for investigating the quark structure of the atom's nucleus - research that will lead to a betterunderstanding of how quarks and gluons make up the nucleus of atoms and the forces that hold matter together.
