3.3. Data base statusData base statusa) Range of data – gaps?

Gaps exist especially in medium and highly ionised high-Z spectral data. For tungsten, results for energy levels and wavelengths could be obtained from EBITs (e.g. Fussmann, Berlin).

For fusion charge exchange data there is still a need for basic cross section calculations by outside groups.

ionisation per photon coefficients S/XB data for boron and tungsten are not (yet) available.

Cross sections for charge-exchange collisions between C ions in different charge state. Atomic data for W, Be.

Work to be done both for short wavelengths and high-Z ions (characteristic of high temperature plasmas) and for long wavelengths and low-Z ions (for divertor plasmas and other plasma sources, e.g. plasma source for ITER neutral beam).

PECs (Photon Emission Coefficients) and ionisation and recombination cross sections for heavy and medium Z species .

Development of time dependent CR models for He & Ar, useful for the measurement of electron density and temperature of the negative ion sources for ITER neutral beam.

Example (1) ADAS contd.Example (1) ADAS contd.

3.3. Data base statusData base statusa) Missing data / variables

The data can often not be used e.g. for divertor and plasma edge modelling, because the underlying raw data (cross sections and differential c.s.) are not (easily) available and hence the condensed data for a particular computer simulation application in the proper format can often not be processed by the user.

The asymptotic behavior of data (cross sections, rate coefficients) e.g. at threshold or at high energies, beyond the tabulated range of Energies / temperatures is often not explicitly made available, with high risk of misuse of data e.g. in dynamic computer modelling applications.

b) Other shortcomingsA lot of theoretical information has already been provided by the ADAS group as well as by outside atomic physicists, but, due to a lack of manpower, there are still substantial gaps.

Low temperature hydrogen molecular kinetics (vibration, excitation,….).Vibrational and electronic excitation of hydrides (CxHy, BeH4, Silanes, etc…..), collisional radiative models for diatomic molecules (C2, CH, ….)

b) Missing data / variablesDatabase developed, but unified formatting and implementation into fusion codes pending. N / N2 collisional radiative model (for plasma edge cooling)Desirable to get some benchmark quantum mechanical calculations for fusion relevant molecules (low priority).

3.3. Data base statusData base statusa) Range of data – gaps? – None at presentb) Missing data / variables – None at present c) Other shortcomings

To facilitate application development from high level languages, advanced interfaces are required from the databases. Such interfaces may be in the form of data access objects for high level languages (like Java or C++) or, preferably, web services. When using multiple data sources inside a single application, it would be very useful to have a common authentication mechanism, in order to reduce the number of passwords required for accessing the data. This can be achieved through generic authentication mechanisms, like PAPI.
