Abstract
A system and method for treating a cavity comprises preparing a superconducting radio frequency (SRF) cavity for removal of a dielectric layer from on an inner surface of the SRF cavity, subjecting the SRF cavity to a heat treatment in order to remove the dielectric layer from the inner surface of the SRF cavity, and preventing the development of a new dielectric layer on the inner surface of the SRF cavity by preventing an interaction between the inner surface of the SRF cavity and atmospheric gasses.
Claims3
A system for treating a cavity comprising:
- a superconducting radio frequency (SRF) cavity with an inner volume defined by an inner surface;
- a vacuum pulling system coupled to the SRF cavity with a vacuum line, and configured to draw a vacuum in the inner volume of the SRF cavity;
- a vacuum connection configured to connect the SRF cavity to the vacuum pulling system;
- a gasket formed between the SRF cavity and the vacuum connection;
- a liquid cooled collar configured to cool the gasket formed between the SRF cavity and the vacuum connection;
- a heating element formed on an exterior of the SRF cavity;
- a support frame comprising vertical members and crossbeams, configured to withstand temperatures to which the SRF cavity is subjected during the heat treatment;
- and
- an oven configured to expose the SRF cavity to a heat treatment wherein the heat treatment removes a dielectric layer from the inner surface of the SRF cavity.
