The microwave autodyne Gunn oscillator as a simple detector of EPR signal for food-irradiation dosimeter

Abstract

A microwave autodyne Gunn oscillator has been presented The oscillator may be used as a simple detector of EPR signal for irradiation-food dosimeter. The idea of EPR method of measurement of radiation dose has been described A low-cost, simple EPR spectrometer for estimation of dose of food irradiation can be built on the basis of microwave autodyne Gunn oscillator. The re-entrant resonator Gunn oscillator has been proposed as an attractive solution of autodyne circuit. The design expressions and the oscillator parameters have been given and one particular oscillator elaborated.
