Title:

Design of Material Insert for Dynamic Nuclear Polarization

Breakthroughs in nuclear physics experiments have led to advancements in particle physics and medical imaging, such as MRI. Dynamic Nuclear Polarization (DNP) is a method used to enhance the sensitivity of nuclear magnetic resonance (NMR) by using microwave irradiation to transfer the polarization of electron spins to nearby nuclei. This process requires a strong magnetic field (5T) and very low temperatures (below 100K). I present the design of a material insert that focuses on efficient cooling of the sample to cryogenic temperatures, improved vacuum sealing, and maximum microwave transmission. The ongoing work at Dr. Santiesteban’s lab aims to refine and optimize existing models to further the progress of DNP experiments. This work has the potential to enhance the signal intensities of NMR, enabling non-invasive, real-time, and faster metabolic imaging in future medical applications.
