| Research Abstract |
The synchrotron radiation is estimated by calculating the radiation transfer taking into account of the relativistic effect, propagation, real torus shape, magnetic structure, and the wall reflection and mode scrambling at the wall. The effects of supra-thermal electron, the wall reflection and mode scrambling on the synchrotron radiation, and dependence of the synchrotron radiation on plasma parameters are evaluated. Since the synchrotron radiation is proportional to 2.5^<th> power of magnetic field, it is effective for decrement of the radiation loss to reduce the magnetic field. That is consistent to the present trend of DEMO reactor design.
