Abstract
A resonator arrangement is provided for electron spin resonance spectroscopy. It comprises an annular, dielectric resonance ring 11 where field lines 13 of the resonance field emerge in the direction of the axis 12 of the resonance ring 11 and close in the outer space 18. There is further provided a coupling means for coupling and decoupling microwave energy into and out of the resonance ring 11. The coupling means comprises a coupling loop 14 which is arranged in the outer space 18 and adapted for being displaced in a direction 16 parallel to the axis 12.
Claims11
A resonator for electron spin resonance spectroscopy, comprising:
- annular dielectric resonance means having an axis and generating a microwave electromagnetic field having field lines extending essentially parallel to said axis within said annular dielectric resonance means and being closed around said annular dielectric resonance means;
- coupling means comprising a coupling loop for coupling microwave energy to and from said annular dielectric resonance means;
- cylindrical shielding means surrounding said annular dielectric resonance means and rigidly connected to said coupling loop;
- and
- means for displacing said shielding means with said coupling loop rigidly connected thereto along a direction parallel to said axis.
