Abstract:
A radio-frequency cavity resonator for applying a radio-frequency magnetic field to a nuclear magnetic resonance target, comprising:a) a conductive longitudinal external shell; b) a first conductive re-entrant longitudinal internal shell, laterally enclosed by the external shell along a first longitudinal extent of the external shell; c) a first generally transverse external annular cap connecting the external shell and the first internal shell; d) a second conductive re-entrant longitudinal internal shell, laterally enclosed by the external shell along a second longitudinal extent of the external shell, wherein a longitudinal separation between the first longitudinal extent and the second longitudinal extent defines a magnetic field target region for applying a generally transverse radio-frequency magnetic field to the target; and e) a second generally transverse external annular cap connecting the external shell and the second internal shell, and situated substantially opposite the first annular cap.
