On Thermalisation of Energetic Charged Particles in Fusion Plasma with Quantum Electrodynamic Considerations

Abstract

Abstract The process of energy loss of charged heavy particles in plasma has been discussed taking into consideration photon emissions by electrons of plasma during scattering as is necessitated by quantum electrodynamics. Although the range in general increases with temperature, it is found that the numerical formula of former treatment giving a range as T3/2 is not in general, obeyed. The range is susceptible to the initial energy as well as mass of the heavy particle as can be seen from the cases of alphas and reaction protons for DT, DD(→p + He3) and D He3 plasmas.
