Abstract
A tubular capacitor with variable capacitance, including a cylindrical tube () of dielectric material, a metallic outer electrode () which surrounds the cylindrical tube (), and an inner electrode which can axially move in the inner bore () of the cylindrical tube () and which abuts the inner bore (), wherein the inner electrode includes a metallic rod ('), located in the inner bore () of the cylindrical tube (), using a rod () of dielectric material. The inventive tubular capacitor has an increased dielectric strength and improves the resolution of NMR spectrometers.
