Oral session 13 - Spherical tokamaks: O12
- Chair: Christos Tsironis
The ST40 tokamak [1], built and operated by Tokamak Energy, is a high field spherical tokamak (ST), B=2.2T at R0=0.4 – 0.5m, A=1.6 – 1.9 with a mission to extend the ST reactor physics basis [2]. Overall energy confinement in STs is largely determined by turbulent electron heat transport, with ion thermal conductivity close to neoclassical levels in higher collisionality H-modes. Electron...
Until recently, theoretical studies in support of the commercial realization of fusion energy mostly focused on research in support of ITER and on the analysis of plasmas in existing tokamaks and stellarators, far from ignition conditions. Recent appearance of privately funded research has advanced alternative concepts, in particular the development of high-beta spherical configuration and...
