Calculation of Ion Orbits in the Divertor/Dipole Regions of the GAMMA10 A-Divertor

Calculation of Ion Orbits in the Divertor/Dipole Regions of the GAMMA10 A-Divertor

The numerical code for calculation of ion orbits was developed in order to calculate the ion orbits in the divertor and dipole regions of the GAMMA10 A-divertor. The flux coordinates (ψ, θ, χ) have been adopted, where the magnetic field B is represented by B = ∇ψ×∇θ = ∇χ. It is found that ion orbits...

Zusammenfassung:The numerical code for calculation of ion orbits was developed in order to calculate the ion orbits in the divertor and dipole regions of the GAMMA10 A-divertor. The flux coordinates (ψ, θ, χ) have been adopted, where the magnetic field B is represented by B = ∇ψ×∇θ = ∇χ. It is found that ion orbits behave chaotic around the magnetic null.
