The ST25 Tokamak for Rapid Technological Development


ST25 (Spherical Tokamak with a major radius 25cm) is a small tokamak device at Tokamak Energy. ST25 was built using conventional copper coils to demonstrate basic properties of a spherical tokamak. It was built as a precursor to ST40 device ST40. There is a subsequent ST25 device, ST25-HTS which uses superconducting coils.
