Kinetic modeling of the transport in the SOL of TdeV during LH current drive and ELM bursts

Abstract

Fully kinetic plasma–neutrals Fokker–Planck code ALLA is used to simulate the transport properties of the scrape-off layer (SOL) plasmas of Tokamak-de-Varennes during lower hybrid (LH) current drive and edge localized modes (ELM) bursts. During LH heating a sizable amount of auxiliary power which is directly deposited into the SOL plasma makes it semi-collisionless. This energy is convected along open magnetic lines directly to the plates, and may be responsible for the hot spots formation. During Type III ELM bursts the detached SOL plasma reattaches to the divertor plates. We find that electron, ion and neutral atom distribution functions are non-Maxwellian for the modeled transient regimes under typical conditions of TdeV SOL plasmas.
