OPEN-ADAS
OPEN-ADAS lets users search atomic data by element, ion, wavelength, or other parameters.
About OPEN-ADAS
OPEN-ADAS is a web system for searching and downloading atomic data from the Atomic Data and Analysis Structure (ADAS), a computer program managed by the University of Strathclyde and developed by a consortium of more than twenty members. Its stated purpose is to make key ADAS data available to non-members with an interest in fusion and astrophysics.
Users can search by freeform query, wavelength, or ion. The site lists fundamental and derived data classes, such as photoionisation cross-sections, photon emissivity coefficients, and beam stopping coefficients. The homepage states that the system's scope is limited to releasing data relevant to general users, along with code, subroutines, and procedures for reading the released files. It does not describe the full ADAS database.
Key features
- Freeform search, plus search by wavelength or by ion
- Download of ADAS atomic data for non-members
- Fundamental data classes, including photoionisation and dielectronic recombination coefficients
- Derived data classes, including photon emissivity and effective emission coefficients
- Code, subroutines, and procedures for reading the released data files
- Nitrogen data files updated with a thermal charge exchange process
Best for: Non-members with an interest in fusion or astrophysics who need ADAS atomic data for their work.
Good for
- Makes ADAS data available to non-members who are not part of the consortium
- Provides reading code and procedures alongside the released data
Watch out for
- Limited to data relevant to general users, so it does not cover the full ADAS database
