Quantum-Based SI Traceable Electric-Field Probe



Joshua A. Gordon, Christopher L. Holloway, Steven R. Jefferts, Thomas P. Heavner


We are presently investigating the feasibility of developing a technique that will allow direct traceable microwave electric field (E-field) measurements. The new approach is based on atomic rf-resonance spectroscopy, where an applied electrical field causes a transition between high-lying Rydberg states of an atom. The new technique will allow direct E-field measurements, traceable to fundamental physical constants and SI units. If successful, this self calibrating probe will provide more accurate field measurements and a better sensitivity than present techniques. Direct traceable E-field measurements with sensitivities below 0.1 V/m could be possible.
