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 the rf power loss (at w values much greater than w(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.
