TBR TBR-II project

A project for the construction of a new tokamak is being developed at the Institute of Physics, University of Sao Paulo. The tokamak named TBR-II will be a medium size tokamak using two high power generators of 15 MW each and concepted as a versatile device for plasma physics research of interest for thermonuclear fusion studies. The main physics objectives are the following: a) study of stability and magnetic confinement properties of plasmas of various shapes (circular, elongated, 'D' and beam shapes), with internal magnetic separatrix. b) transport and diffusion research beginning initially with Ohmic heated plasma and followed with auxiliary heated plasma. c) radio-frequency and NBI auxiliary heating, and plasma current generation with strong power injection of about 10 times the Ohmic power. d) study of MHD instabilities and disruptions by the use of helical windings and EML (Ergodic Magnetic Limiters). The details of the physics objectives and device construction strategies will be covered by this presentation. (Author)
