Ryan J Ringle

Ryan J Ringle serves as a Fixed Term Associate Professor within the Department of Physics & Astronomy at Michigan State University, where he conducts experimental nuclear physics research primarily at the National Superconducting Cyclotron Laboratory (NSCL) and associated facilities. His work bridges fundamental nuclear structure studies with instrumentation development for rare isotope beam applications.

Dr. Ringle's research program centers on precision mass spectrometry of short-lived radioactive nuclei using Penning trap techniques, with significant focus on beta decay studies, double beta decay investigations, and nuclear astrophysics applications. He specializes in developing advanced beam handling systems including gas catchers, beam coolers, and specialized Penning traps that enable high-precision measurements of exotic nuclei. His technical expertise spans ion beam dynamics, cryogenic systems, and ultra-sensitive detection methods essential for rare isotope research.

Analysis of his recent publications (2017-2019) reveals consistent advancement in Penning trap mass spectrometry capabilities, particularly through the Low-Energy Beam and Ion Trap (LEBIT) facility. His work demonstrates increasing sophistication in measuring ultra-low Q-value decays, testing fundamental symmetries, and providing critical nuclear data for astrophysical models. The research consistently addresses instrumentation challenges while delivering high-impact nuclear physics results that constrain theoretical models.

Dr. Ringle maintains active roles in multiple experimental teams at MSU's nuclear physics facilities, including leadership in the Advanced Cryogenic Gas Stopper project and contributions to the Beam Cooling and Laser Spectroscopy (BECOLA) collaboration. His work directly supports the scientific mission of the Facility for Rare Isotope Beams (FRIB), where his instrumentation developments enable next-generation experiments in nuclear structure, astrophysics, and fundamental interactions.
