Abstract [en]

A collisionless model for fast-ion transport in a tokamak

reactor is derived from first principles, and a new orbitfollowing

code is developed to simulate this model. Results

from the model applied on two scenarios of DT fusion

plasmas, one from ITER and one from JET, are compared,

and the prompt losses as well as the effects of orbit

shapes are quantified; it is shown that both the prompt

losses and the orbit effect on confined particles are very

small in both reactors. Although some problems are still

present, the method presented shows potential for further

investigating orbit effects.

Abstract [sv]

En modell för kollisionsfri transport av högenergetiska

joner i tokamaks har tagits fram, och en ny banlösande

kod har utvecklads för att simulera denna model. Resultat

från modellen applicerad på två scenarion med DTplasma,

ett från ITER och ett från JET, jämförs, och omedelbara

förluster samt effekter av inneslutna banors form

kvantifieras; både ban- och omedelbara förluster visas vara

mycket små i båda reaktorerna. Även om mindre problem

återstår att lösa, har metodent pontential för att vidare

undersöka baneffekter i fusionsplasman.
