Bicoherence analysis of nonstationary and nonlinear processes
Peter Zsolt Poloskei, Gergely Papp, Gabor Por +2
Bicoherence analysis is a well established method for identifying the quadratic nonlinearity of stationary processes. However, it is often applied without checking the basic assump…
Dynamics of positrons during relativistic electron runaway
Ola Embréus, Linnea Hesslow, Mathias Hoppe +3
Sufficiently strong electric fields in plasmas can accelerate charged particles to relativistic energies. In this paper we describe the dynamics of positrons accelerated in such el…
Generalized collision operator for fast electrons interacting with partially ionized impurities
L Hesslow, O Embréus, M Hoppe +4
Accurate modelling of the interaction between fast electrons and partially ionized atoms is important for evaluating tokamak disruption mitigation schemes based on material injecti…
Effect of partially ionized impurities and radiation on the effective critical electric field for runaway generation
Linnea Hesslow, Ola Embréus, George J Wilkie +2
We derive a formula for the effective critical electric field for runaway generation and decay that accounts for the presence of partially ionized impurities in combination with sy…
