Abstract

The design, engineering parameters, and EPR performance of ceramic re-entrant resonators optimized for L-band EPR imaging of biological samples are reported. Modified equivalent schematics and resonant frequency expressions for the three-loop two-gap re-entrant resonator design are presented. Fabrication techniques and test data for two resonators with a resonant frequency of approximately 1.2 GHz are provided. The unique properties of ceramics enabled the development of a highly stable and highly sensitive re-entrant resonator design of minimum thickness optimally suited for EPR imaging experiments. This resonator yields a signal-to-noise ratio at L band as high as that of X-band cavities for a given-concentration aqueous radical solution of unlimited volume.
