Non-Resonant Electron Spin Resonant Probe And Associated Hardware

NIST Inventors

Jason Campbell , Jason Ryan , Kin (Charles) Cheung , Robert Gougelet and Pragya Shrestha

This invention details a non-resonant probe designed to measure changes in the density of broken bonds (unpaired electrons) in materials exposed to ionizing radiation. The probe functions to excite and detect electron spin resonance transitions in these materials. Accumulated radiation dose can then

Phase Shift Detector Process for Making and Use of Same

NIST Inventors

Kin (Charles) Cheung , Jason Ryan and Jason Campbell

The detector senses very small phase shifts in a highly balanced microwave bridge. An electric field optimized microwave probe, in close proximity to a sample, serves to perturb the degree of bridge balance due to a .change in effective dielectric constant of the sample. The major innovation
