摘要：

Interpretative modelling of the JET SOL plasma using the onion-skin method (OSM) has provided valuable insights into relationships between edge plasma parameters and information about the anomalous cross-field energy transport coefficients. The method relies on solving the plasma transport equations along individual flux surfaces, and adjusting the cross-field source terms to best match the Langmuir target probe profiles. In this paper, an improved solver (OSM2) is described and three sets of results are presented: code-code comparison with EDGE2D, code-experiment comparison with reciprocating probe (RCP) data on JET MkIIGB, and detailed simulation of a 12 MW ELMy H-mode on MkIIGB.
