SOFT: A synthetic synchrotron diagnostic for runaway electrons
Mathias Hoppe, Ola Embréus, R. Alexander Tinguely +3
Improved understanding of the dynamics of runaway electrons can be obtained by measurement and interpretation of their synchrotron radiation emission. Models for synchrotron radiat…
On the relativistic large-angle electron collision operator for runaway avalanches in plasmas
Ola Embréus, Adam Stahl, Tünde Fülöp
Large-angle Coulomb collisions lead to an avalanching generation of runaway electrons in a plasma. We present the first fully conservative large-angle collision operator, derived f…
Effect of partially-screened nuclei on fast-electron dynamics
Linnea Hesslow, Ola Embréus, Adam Stahl +4
We analyze the dynamics of fast electrons in plasmas containing partially ionized impurity atoms, where the screening effect of bound electrons must be included. We derive analytic…
Runaway-electron formation and electron slide-away in an ITER post-disruption scenario
A. Stahl, O. Embréus, M. Landreman +2
Mitigation of runaway electrons is one of the outstanding issues for the reliable operation of ITER and other large tokamaks, and accurate estimates for the expected runaway-electr…
NORSE: A solver for the relativistic non-linear Fokker-Planck equation for electrons in a homogeneous plasma
A. Stahl, M. Landreman, O. Embréus +1
Energetic electrons are of interest in many types of plasmas, however previous modeling of their properties has been restricted to the use of linear Fokker-Planck collision operato…
Effect of bremsstrahlung radiation emission on fast electrons in plasmas
Ola Embréus, Adam Stahl, Tünde Fülöp
Bremsstrahlung radiation emission is an important energy loss mechanism for energetic electrons in plasmas. In this paper we investigate the effect of spontaneous bremsstrahlung em…
