Kinetic modelling of runaways in fusion plasmas
Conference contribution, 2016

Mitigation of runaway electrons is one of the outstanding issues for a reliable operation of ITER and other large tokamaks. To achieve this, quantitatively accurate estimates for the expected runaway electron energies and current are needed. In this work we de- scribe an accurate theoretical framework for studying the effects of collisional nonlinear- ities, bremsstrahlung and synchrotron radiation emission, and knock-on collisions on the runaway electron distribution. We outline the identification of significant features of run- away electron behaviour enabled by this framework and their potential to affect the growth of a runaway population.
