US 6,208,227 B1 · Electromagnetic resonator

Abstract

An electromagnetic resonator has a resonant element made of a high-temperature superconducting material such as YBa2Cu3O7−x. The resonant element has a substrate coated with a thermally conductive layer such as silver, over which the high-temperature superconductor material is placed. The thermally conductive layer distributes heat along the length of the resonant element to minimize the effects of localized heating at, for instance, the center of the resonator. The resonant element is held to a housing by a mounting mechanism including a post made of polycrystalline alumina. The polycrystalline alumina transfers heat away from the center of the resonant element and may be used to suppress spurious response due to second harmonic resonance.

Dependent claims

A resonator mounting mechanism for attaching a resonant element to a wall in a resonator cavity, the mounting mechanism comprising:

a post comprised of a low dielectric loss thermally conductive material having a first end adapted to receive the resonant element and a second end having a flat bottom surface;
and
a base comprised of a material different than the post connected to the post near the bottom surface of the post;
wherein the base holds the post to the cavity wall with the bottom surface of the post in contact with the wall to transmit heat from the first end of the post to the second end of the post and through the post to the cavity wall.
