Influence of detailed neutral particle modelling on currents and cross-field drifts in a poloidally biassed divertor plasma
The application of external electrostatic fields to divertor and limiter configurations provides some control of plasma behaviour in general and of scrape-off layer profiles. The analysis of such a control mechanism on larger devices requires plasma edge codes which are capable of computing electric currents and electric fields. Therefore, the B2-edge plasma code is modified to include the effects of classical fluid drifts across the magnetic field lines and electric plasma currents. In this paper this extended code (EB2) is used to examine effects of electrical biasing between divertor plates. In addition, the EB2 code is coupled with the Monte Carlo code EIRENE to describe more accurately the neutral particle behaviour. Differences between a simplified analytic and a Monte Carlo model are investigated.
