The bootstrap fraction, I{sub bs}/I{sub p}, and the shape of the bootstrap current density, J{sub bs}(r), can depend sensitively on the shape of the plasma profiles. Beginning with Hirshman`s form for the bootstrap current density, and making a large aspect ratio expansion (proceeding two orders...

Bootstrap current is regarded as a serious candidate for non-inductively driving a significant fraction of the total current. High bootstrap fraction discharges have already been achieved and analysed in several tokamaks, including JT-60, DIII-D and TFTR. Tore Supra (R=2. 36 m, a=0.80 m) is...

The effects of the radial electric field E/sub r/ on the bootstrap current in ATF-type configurations are studied with the Drift Kinetic Equation Solver (DKES). It is found that there is a range of E/sub r/ values over which the bootstrap current does not depend on E/sub r/. The effects of E/sub...
