Comparing plasma population kinetics codes: Review of the NLTE-3 Kinetics Workshop
TLDR
It was found that good agreement between codes and with experiments is observed near closed shells, but significant differences exist otherwise, or when density effects are important, as well as plans for the next workshop and for a kinetics database.Abstract:
Comparison of plasma population kinetics codes, which has become an important tool for their testing and verification, was the subject of the third Non-LTE Code Comparison Workshop held at the National Institute of Standards and Technology in December 2003. The motivations for the workshop are presented here, together with its technical organization. The cases studied range from carbon to gold, and include both steady-state and time-dependent calculations. The set of results represents the current capabilities in kinetics modeling, and illustrates the effectiveness of this workshop approach to code comparisons. It was found that good agreement between codes and with experiments is observed near closed shells, but significant differences exist otherwise, or when density effects are important. On a more general level, we discuss how to meaningfully compare kinetics data. We conclude with plans for the next workshop and for a kinetics database.read more
