Abstract
A resonator is provided for electron spin resonance spectroscopy. It comprises a resonant element comprising a cavity, and a predetermined oscillation mode is capable of propagating in the cavity. The resonator comprises further a coupling element comprising a waveguide section. Finally, the resonator is equipped with a tuning arrangement for coupling an electromagnetic wave in the waveguide section with the oscillation mode in the cavity. The tuning arrangement comprises at least one conductive wafer, which is arranged at the free end of a tuning rod projecting into the waveguide section and is adapted for displacement in the direction of a longitudinal axis of the tuning rod. The wafer further coacts with a coupling element disposed between the waveguide section and the cavity. Two wafers are arranged on either side of the coupling element, in the direction of the longitudinal axis, and can be displaced in opposite senses relative to the coupling element.
