ST40 does not use HTS magnets. The magnets are made from copper and LN2 cooled. The company is demoing HTS magnets but has not used them in a working tokamak.
ST25 HTS did as far as I can tell — unless TE are lying, but that seems improbable.
ST25 was a "desktop tokamak" measuring 25cm in diameter.
Am no physicist, but was wondering about that. Thought this was all done before by different fusion companies?
The point is the high temperature superconducting magnets. Creating a tokamak plasma is not novel.
