Eliminating poor statistics in Monte-Carlo simulations of fast-ion losses to plasma-facing components and detectors
Eero Hirvijoki
With Wendelstein 7-X now up and running, and the construction of ITER proceeding, predicting fast-ion losses to sensitive plasma-facing components and detectors is gaining signific…
Differential formulation of the gyrokinetic Landau operator
Eero Hirvijoki, Alain J. Brizard, David Pfefferlé
Subsequent to the recent rigorous derivation of an energetically consistent gyrokinetic collision operator in the so-called Landau representation, this paper investigates the possi…
Calculating the 3D magnetic field of ITER for European TBM studies
Simppa Äkäslompolo, Otto Asunta, Thijs Bergmans +6
The magnetic perturbation due to the ferromagnetic test blanket modules (TBMs) may deteriorate fast ion confinement in ITER. This effect must be quantified by numerical studies in…
Bump formation in the runaway electron tail
J. Decker, E. Hirvijoki, O. Embreus +4
Runaway electrons are generated in a magnetized plasma when the parallel electric field exceeds a critical value. For such electrons with energies typically reaching tens of MeV, t…
Numerical calculation of ion runaway distributions
Ola Embréus, Sarah Newton, Adam Stahl +2
Ions accelerated by electric fields (so-called runaway ions) in plasmas may explain observations in solar flares and fusion experiments, however limitations of previous analytic wo…
