The extensive high quality fundamental and derived atomic data for fusion generated in association with the ADAS Project and in the ADAS databases are a major resource. It is beneficial for this to be in the public domain, freed from the restriction of ADAS membership, as a guided provision. This provision is the core thrust of OPEN-ADAS.

OPEN-ADAS allows for the download of a selected set of ADAS data and associated reading routines for them. OPEN-ADAS is a joint development between the ADAS Project and the IAEA.

The key data classes included within OPEN-ADAS are:

ADAS has around fifty distinct data classes. Data excluded from OPEN-ADAS include "driver" files, opacity data, superstage/partitioned data and others. Reasons for exclusion include only being useful with an interactive system, availability elsewhere and the need for expert guidance on the use of certain data. In broad terms, data from OPEN-ADAS may not be re-distributed without permission.

The terms and conditions of using OPEN-ADAS can be found here.
