Temperature dependence of synchrotron radiation current drive in inhomogeneous tokamak plasmas
There is increasing interest in the concept of an advanced fuel tokamak reactor at large toroidal current. The concept of a high current reactor would be enhanced if passive non-inductive methods of current drive could be found to supply a significant part of the total current. In this paper, current drive by asymmetric synchrotron radiation in high temperature inhomogeneous tokamaks is discussed and the global normalised efficiency as a function of the peak density and temperature and profile indices is obtained. The computation shows that synchrotron radiation in a hot reactor can drive a significant part of the total current to be used as a seed for bootstrap current.
