Databases

The Atomic and Molecular Data Unit manages several numerical and bibliographic databases for fusion and other plasma science research:

• AMBDAS: Atomic and Molecular Bibliographic Data System
• AMBDAS: Legacy interface
• ALADDIN: Numerical database of evaluated collisional cross sections and plasma-material interaction data
• CollisionDB: Numerical database of collisional data
• CascadesDB: Database of Molecular Dynamics simulations of collision cascades in materials of relevant to fusion research
• DefectDB: Database of DFT calculations of radiation-induced defects in nuclear-relevant materials
• pwiDB: Database of plasma-wall interaction data for fusion energy research
• Clerval: Database of institutions, people and events related to atomic and molecular data

Classification of Collisional Processes

The Nuclear Data Section issues a set of classifications of plasma processes for use in databases and other resources. The most recent version, 2.5, is an update on the document released after the AMD Unit's 2019 meeting on Software Tools for Atomic and Molecular Databases.

Molecular Quantum Number Descriptions

A list of quantum numbers used to describe the states of molecules and molecular ions was agreed as part of the Virtual Atomic and Molecular Data Centres (VAMDC) project, which developed the XSAMS Schema.

Documentation and description of the molecular quantum number "cases" is available here.

ORNL "Red Book" Series: Atomic Data for Fusion

The Controlled Fusion Atomic Data Center (CFADC) at Oak Ridge National Laboratory (ORNL) produced a series of printed compilations of atomic data for fusion applications known as the "Red Books". Since its closure, scanned versions of some of these reports have been difficult to find – they are provided for download below as a convenience to the fusion data community.
