Abstract

The transport code ASTRA (an Automatic System for Transport Analysis in a Tokamak) was developed at the Kurchatov Institute for Atomic Energy, Moscow, several years ago to analyse plasma transport in tokamaks. Since that time the code has appeared to be a powerful tool applicable to various tasks, such as predictive transport modelling, analysis of experimental results, study of scenarios, and examination of theoretical transport models. This paper deals with transport simulations fulfilled with a version of the ASTRA code extended for stellarators. Stellarator neoclassical transport models of Beidler, Kovrizhnykh, Hastings-Houlberg-Shaing and Maaßberg were included in the stellarator version of the code. The ambipolar radial electric field is calculated in all these cases self-consistently. Results are presented for such devices as Wendelstein 7-AS and a Helias reactor.
