Serpent neutronics model of Wendelstein 7-X for 14.1 MeV neutrons
Simppa Äkäslompolo, Jan Paul Koschinsky, Joona Kontula +8
In this work, a Serpent 2 neutronics model of the Wendelstein 7-X (W7-X) stellarator is prepared, and an response function for the Scintillating-Fibre neutron detector (SciFi) is c…
Synthetic fast ion diagnostics in tokamaks: comparing the Monte Carlo test particle code ASCOT against experiments
Simppa Äkäslompolo, Taina Kurki-Suonio, Seppo Sipilä +1
Measuring fast ions, most notably fusion alphas, in ITER and future reactors remains an issue that still lacks an adequate solution. Numerical simulations are invaluable in testing…
High-performance orbit-following code ASCOT5 for Monte Carlo simulations in fusion plasmas
Jari Varje, Konsta Särkimäki, Joona Kontula +5
We present a novel implementation of a Monte Carlo particle-following code for solving the distribution function of minority species in fusion plasmas, called ASCOT5, and verify it…
Validating the ASCOT modelling of NBI fast ions in Wendelstein 7-X stellarator
S. Äkäslompolo, P. Drewelow, Y. Gao +37
The first fast ion experiments in Wendelstein 7-X were performed in 2018. They are one of the first steps in demonstrating the optimised fast ion confinement of the stellarator. Th…
Simulations of fast ion wall loads in ASDEX Upgrade in the presence of magnetic perturbations due to ELM mitigation coils
Otto Asunta, Simppa Äkäslompolo, Taina Kurki-Suonio +4
The effect of ASDEX Upgrade (AUG) ELM mitigation coils on fast ion wall loads was studied with the fast particle following Monte Carlo code ASCOT. Neutral beam injected (NBI) parti…
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…
