Enhancement of Synchrotron radiation loss in a reactor caused by plasma turbulence

Abstract

The role of the slide-away electron tail generated by plasma turbulence on the emission and absorption of synchrotron radiation in a tokamak reactor is investigated. It is shown that rf power loss at {omega} >> {omega}{sub c} is radiated by electrons with velocities significantly greater than the thermal speed; therefore, enhancement of the synchrotron radiation loss can occur if the tail temperature is greater than that of the Maxwellian bulk. A method for determining the local tail temperature in a tokamak device based on the transmission interferometry approach is also discussed.
