Abstract:
A resonance apparatus for super-Q detection comprising:a probe for detecting a resonance signal induced in a sample; said probe comprising a coil; wherein said probe forms a tuned tank circuit; wherein the bandwidth of said probe is narrower than the bandwidth of said resonance signal; wherein the probe has a Qprobe=fprobe/&Dgr;fprobe, wherein fprobe is the resonant frequency of the probe, and &Dgr;fprobe is the full width at half height (FWHH) bandwidth of the probe; wherein the resonance signal has a QRS=f0/&Dgr;fRS, wherein f0 is the center frequency for the resonance signal, and wherein &Dgr;fRS is the FWHH bandwidth of the signal; and wherein the ratio Qâ€²=Qprobe/QRS is greater than one.
