“…Some codes have been utilizing this method to investigate kinetic effects in edge plasmas, e.g. PARASOL [40,41,42,43,44,45,34,46,47,48], BIT [49,50,51,52,53,54,55,56,57], W1 and W2 [58,59,60].…”

Power exhaust is one of the critical issues for future fusion devices, e.g. ITER.The calculation of power deposition is critical for the divertor design. SOLPS is the main tool for predictions of the Scrape-off Layer (SOL) and divertor conditions in the future fusion device ITER, where parallel kinetic effects in the SOL will play an important role. SOLPS uses a collisional fluid model which does not take kinetic effects into account. The present work has enabled SOLPS in its 1D version to incorporate electron kinetic effects by coupling it with the Kinetic Code for Plasma Periphery (KIPP). An iterative algorithm, which is made as an automatic process, is investigated in this work.

Kinetic modelling of parallel plasma and heat flows in the scrape-off-layer (SOL) is presented. Detached [l-41 and attached regimes are studied. A kinetic Edge Localized Mode (ELM) [5] model is simulated by temporally varying the incoming heat power from the core. Deviations of the plasma distribution .functions from Maxwellian are observed. Our simulations are performed using the collisional PIC code W1 [6], which employs a non-stationary 1D2V fully kinetic model of a high recycling SOL plasma.

Fluid descriptions can fail for fast processes such as Edge Localized Mode (ELM) [l] bursts because plasma transport properties may be affected by incomplete Maxwellization of plasma particles. In this case only kinetic plasma descriptions of ELMs can give qualitatively correct results. In the present work we propose three different models of ELM propagation in the scrape-off-layer (SOL). We also present the first results of the kinetic modeling of the propagation of ELM bursts along the magnetic field, towards the target in a SOL plasma. These simulations are performed with a 1D2V finite element Fokker-Planck code ALLA [2] and with a 2D PIC code W2 [3].
