OPEN-ADAS is a system to search and disseminate key data from the Atomic Data and Analysis Structure (ADAS).
ADAS is a computer program managed by the University of Strathclyde and made up of a consortium of over twenty members.
The OPEN-ADAS system enables non-members, with an interest in fusion and astrophysics, to download and use ADAS data.More about OPEN-ADAS
Dielectronic and radiative recombination from the papers III and IV are available. Read more
The data contained within ADAS is strictly organised and precisely formatted. There are over fifty distinct types of data file. The scope of OPEN-ADAS is targetted on and limited to the release and organisation of general user relevant data from the ADAS databases and the provision of code, subroutines and procedures to enable such users of OPEN-ADAS to read the released data. These data classes are given below.
nl-resolved charge exchange cross-sections over a range of n-shells for a donor neutral atom and ionised impurity receiver
Coefficient data for a given ion which includes spontaneous emission coefficients and electron impact collisional rates and other optional processes.
Collections of Maxwell averaged electron impact ionisation rate coefficients for both direct ionisation and excitation/autoionisation.
Maxwell-averaged radiative recombination coefficients i.e. spontaneous free-bound transitions of Maxwellian electrons excluding dielectronic recombination.
Collections of state-selective dielectronic recombination coefficients of Maxwellian free electrons resolved by initial and final metastable and captured n-shell.
Fundamental data for inner shell excitation followed by autoionisation
Fundamental data for direct (including and especially inner shell) photoionisation.
Partial final-state resolved radiative recombination rate coefficients from both ground and metastable levels.
Effective (collisional–radiative) coefficients which are required to establish the ionisation state of a dynamic or steady-state plasma.
Collections of effective emission coefficients for spectrum lines emitted by ions of elements following charge transfer from neutral beam donor atoms.
Data collections useful in analysis of a spectrum line from an ionisation stage of an element, which is inflowing into a plasma from a surface.
Fully density dependent and metstable resolveed effective emissitivy coeffeicients from a collisional–radiative model.
They are effective ionisation coefficients, including charge transfer losses, which leave the beam atoms ionised.
Coefficients for the emission from a beam when it enters an ionised plasma including impurities. Results are fully density dependent output from a collisional–radiative model.
