Abstract:
1. A cryogenic resonator system, which is coupled to a NMR spectrometer and to a RF switch power source, comprising: a cryogenic multimode resonator having a first resonant mode resonating at a first resonant frequency tuned to an operating frequency of the NMR spectrometer and at least a second resonant mode resonating at a second frequency tuned to a frequency of the RF switch power source; and at least one superconducting RF switch formed within at least one section of said cryogenic multimode resonator, wherein RF current induced by the RF switch power source in said at least one superconducting RF switch approaches or exceeds a value of a critical RF current thereby increasing a resistance of said at least one superconducting RF switch and casing a reduction of a Q-factor of the cryogenic multimode resonator.
