Resonator arrangement for electron spin resonator spectroscopy - contains dielectric resonance ring coupler with coupling loop movable in parallel with ring axis

摘要

Resonance field lines (13) align with the resonance ring (11) axis (12) and close in the outer space (18). Microwave energy is coupled into and out of the ring via a coupler. The coupler contains a loop (14) arranged in the outer space. This loop is mounted at an axial and/or radial distance from the resonance ring and is enclosed by a cylindrical screen. ADVANTAGE - By adjusting coupling arrangement larger range of resonator Q can be covered.
