Abstract

It is reasonable to believe that plasmas in thermonuclear reactors will have to be steady state. In the case of tokamaks this requires a large amount of recirculated power to maintain the plasma current. However a part of this current, the bootstrap current, is expected to be generated by the plasma itself. The concept of a reactor with 100% bootstrap current obtained by monitoring the n(e) and T(e) profiles is presented. This study concludes that its viability depends on a low particle and heat transport in the plasma centre and also, that the plasma current will relax repeatedly around a state of flat q=1 profile in the central region.
