Because of more important plasma chemistry
(increased non-linearity, non-locality, in sources).
IAEA
• Data needs to be “verified” by an expert
• Data needs to be “robust”
• Data needs to be “comprehensive”
• Data needs to be easy to use
• Version control: know what data was used for a particular run, and
which runs used a particular version of the data
• Needs to be efficient
• Needs to be able to address special needs
Requirement for Plasma Modelling: Reliable data sets for AMNS data
Require a Recommended & Internationally Agreed Library for
Atomic, Molecular, Nuclear, Surface Data
IAEA
For Nuclear Data:
Compilation, Evaluation and Dissemination
• Nuclear Reaction Data

and currently charged particle data and
higher energies
