Title: Gianluigi Ciovati: Innovator in Superconducting Technology
Introduction
Gianluigi Ciovati is a prominent inventor based in Yorktown, VA (US), known for his contributions to superconducting technology. He holds 2 patents that showcase his innovative approach to enhancing particle accelerators and superconducting materials.
Latest Patents
Ciovati's latest patents include a high-current conduction cooled superconducting radio-frequency cryomodule. This advanced cryomodule is designed for particle accelerators and can accelerate an electron beam of average current up to 1 ampere in continuous wave (CW) mode or at a high duty factor. The cryomodule features a single-cell superconducting radio-frequency cavity made of high-purity niobium, with an inner coating of NbSn and an outer coating of pure copper. Conduction cooling is achieved through multiple closed-cycle refrigerators, while power is fed into the cavity by two coaxial couplers. Additionally, damping of high-order modes is accomplished using a warm beam-pipe ferrite damper.
Another significant patent by Ciovati involves passivated niobium cavities. This invention provides a niobium cavity that exhibits high quality factors at high gradients. The process includes removing surface oxides through plasma etching, eliminating absorbed gases by high-temperature treatment under ultra-high vacuum, and ensuring long-term chemical stability by applying a passivating layer of a superconducting material with a higher superconducting transition temperature than niobium. A preferred embodiment of this layer comprises niobium nitride (NbN) applied by reactive sputtering.
