Abstract
A capacitively shortened coaxial resonator for making nuclear magnetic resonance measurements includes inner and outer concentrically arranged metal cylinders. The cylinders define therebetween a sample region and are shorted electrically by a conductive cap which closes one end of the inner and outer cylinders. A capacitor is connected across the cylinders at the opposite open end and functions to resonate with the inductance of a coaxial conductor formed by the short circuited cylinders. Samples placed in the sample region are mounted on an air bearing and rotated by means of air holes formed in the inner and outer cylinders.
