Abstract
The high-beta poloidal discharge number 17110 in JT-60U that develops an internal transport barrier is analysed for the transport of ion ene rgy and momentum. First the classical ion temperature gradient stabili ty properties are calculated. Then the evolving toroidal and poloidal velocity profiles reported by Koide et al (1994 Phys. Rev. Lett. 72 36 62) are used to show how the sheared hows control the stability and tr ansport. Coupled momentum-energy transport equations predict the creat ion of a transport barrier.
