TL;DR: A review of the status of various approaches dealing with tokamak edge related issues by employing two-dimensional numerical fluid codes for the main components of the edge plasma is given in this article.

TL;DR: In this paper, the 2D multifluid edge code B2 coupled with the 3D neutral gas Monte Carlo code EIRENE is used for edge interpretation and model validation on the axisymmetric poloidal divertor experiments ASDEX and ASDEX-Upgrade.

TL;DR: In this article, the spectral profile of Hα emitted in front of a TEXTOR limiter has been measured with a high resolution spectrometer and calculated with the EIRENE code.

TL;DR: In this article, the authors compared helium transport and exhaust in L-mode and in an enhanced confinement regime (H-mode), which is induced by a polarizing electrode, have been made for the TEXTOR tokamak.

TL;DR: In this article, collision data for elastic scattering of H 2 -H + are calculated using a Morse-like potential, which can be used in Monte Carlo calculations, an example of which will be shown.

TL;DR: In this article, the charge exchange (CX) neutral energy distributions from ASDEX measured with the conventional neutral particle analyzers (NPA) at energies >500 eV are combined with the low energy CX spectra from the low-energy neutral analyzer (LENA).

TL;DR: In this paper, the influence of different neutral particle source term models of various degrees of sophistication, ranging from the original minimal analytic description in B2 to the fully three-dimensional Monte Carlo code EIRENE, was evaluated by comparing the BRAAMS (B2) code with other edge transport codes, and the assumption of ambipolarity and the absence of diamagnetic fluxes was investigated.

TL;DR: In this paper, an analytical solution to a one-dimensional linear kinetic transport equation (slab model) is obtained to investigate the influence of elastic collisions between neutral atoms and plasma ions on neutral gas transport under typical tokamak boundary conditions.
