Investigation of the first wall reflectivity and related synchrotron radiation loss and current drive in tokamaks
The first wall reflectivity and the correlated synchrotron radiation loss and current drive in high central electron temperature tokamak plasmas are investigated. It is shown that the reflection coefficient can be determined from the frequency of maximum emission. In particular, the differential reflectivity with respect to the magnetic field correlated with the toroidal current generated by a fish-scale structure is proportional to the relative shift of frequencies. It is pointed out that experimental investigation of the first wall reflectivity suited for synchrotron radiation current drive can be performed in existing devices at moderate electron temperatures.
