NMR Polarization Measurements for Jefferson Lab's Solid Polarized Targets

Abstract

Solid polarized targets rely on Nuclear Magnetic Resonance techniques to provide accurate measurements of the enhanced polarization provided by Dynamic Nuclear Polarization. Upcoming polarized target experiments in Jefferson Lab's Hall B present challenging conditions which demand improvements to traditional NMR methods. We will discuss the changes prompted by the new Hall B target, lay out plans for improvements to our NMR system, and show results of initial tests of our designs.

“…To further facilitate tests focused on NMR performance, we use epoxy in place of traditional target material, which can have coils directly embedded within it to maximize coupling, and can be doped with TEMPO [11] to allow polarization via DNP. A discussion of our first demonstration of this 77 K approach to NMR tests is found in previous proceedings [12].…”
