Fusion Pioneer Rod Bateman HTS
Ғылым және технология
High temperature superconducting (HTS) magnets open the pathway to commercial fusion energy from a spherical tokamak device. In this week’s Fusion Pioneer video, Dr Rod Bateman, our Magnet Development Manager, explains why HTS' capacity to operate in a high background field is so important for the design of future fusion power plants.
"The greatest challenge solved so far is the development of high-temperature superconducting magnets that are suitably robust and compact so that they can enable a spherical tokamak”, says Rod. “This means that future fusion power plants can be compact and efficient-and hence commercially viable."

Can you explain the cooling setup you use? How do you get down to 20K without Liquid Helium?

You can get down to 20K using a cryocooler, which works via the compression and expansion of a gas. These are already used in various industries, such as medical and scientific research. You don't need the specialist cryogenic facilities you'd need to use liquid helium. Hope that helps!

👍👍🤌
I'm not convinced any of the many pulse plasma generators are practical or cost efficient. A sustained magnetic field under dynamic control is the way to go.

I would disagree. Have you not considered the isotope effect, and that the critical temperature for many superconductors depends on the isotopic mass, indicating that lattice vibrations are involved in the superconductivity, and that the attractive coupling between electrons is through the lattice vibrations ? Ringing any bells? Sometimes it's wiser to allow people to suspect one's foolishness rather than to break cover and remove all doubt.
