Analytic description of energy loss by a bounded inhomogeneous hot plasma due to the emission of electromagnetic waves
Universal formulas for total power losses by bounded media due to the emission of electromagnetic (both transverse and longitudinal) waves in the regimes of nonlocal (non-diffusive) heat transport are proposed. In particular, these universal formulas generalize Trubnikov's formula for synchrotron losses to the case of arbitrary emission/absorption process and inhomogeneous nonstationary plasma. Their derivation is based on a non-diffusion method which generalizes the "escape-probability method" in the theory of radiative transfer in resonance atomic lines (RTRAL). The results suggest a qualitative model for the global heat transport in a tokamak.
