"Probing Polarized Nuclei to Explore the Structure of Matter"

James Maxwell , Jefferson Lab
[Host: Kent Paschke]

Since the failure of classical mechanics at subatomic scales, understanding the spin of fundamental particles has been central to the investigation of the most basic workings of matter. Beyond a key property for study, spin has become an indispensable instrument for experimental discovery in the form of polarized beam sources and scattering targets. As physicists have turned from the successful description of the weakly bound, perturbative regime of QCD toward unraveling the mysteries of confinement and the glue, ever-improving polarized tools are as crucial as ever. This talk will give an overview these tools, emphasizing solid polarized targets for leptonic probes of QCD, covering their operation, development and upcoming experimental use. With the promise of a nuclear physics facility for e-N collisions on the horizon, I will discuss a new technique to produce a polarized He3 beam source. Finally, a new search for exotic glue in the nucleus using polarized targets and sources will be introduced.
