Description
The University of New Hampshire polarized target lab uses dynamic nuclear polarization to achieve high tensor polarization in solid deuterated target material, such as ND3 and deuterated alcohols. This system is comprised by a number of subsystems including a 1 K liquid helium refrigerator, a solid state microwave emitter, and a superconducting magnet. During periodic “cool-downs” polarization data is collected using an NMR analyzer. The polarization can be extracted using a curve-fitting method designed to fit the characteristic doublet lineshape of spin-1 nuclei such as deuterons. In this presentation I will explain the methods used by the UNH polarized target group to perform dynamic nuclear polarization and tensor enhancement and show a small sample of polarization data taken by the UNH polarized target group between September 2024 and May 2025.
