  10. Comment on Data Base Interface EU ITM Task Force (P. Strand) Support to extend the Universal Access Layer backend or alternatively to create a set of standalone filters that would provide the connectivity or filter from the different experiments to the ITM-TF database and structures. This UAL should in principle cover all DB’s Knud Thomsen 23 Feb 2007 CSA Information Workshop

  11. Example (1) ADAS • Data base access • Internet access - yes • Relational database • Restricted access (Open-ADAS free?) • Subscription fee • Data base use • Documentation - yes • User manual - yes • Data base tools - yes • Data base interface - yes In general the access to the data is for a non-ADAS professional user not easy and the data format needs a thorough reading of the instruction manual (for e.g. to distinguish single lines from multiplets). One would wish more user friendly inputs/outputs. (User training ?) Knud Thomsen 23 Feb 2007 CSA Information Workshop

  12. Example (1) ADAS contd. • Data base status • Range of data – gaps?Gaps exist especially in medium and highly ionised high-Z spectral data. For tungsten, results for energy levels and wavelengthscould 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. Knud Thomsen 23 Feb 2007 CSA Information Workshop

  13. Example (1) ADAS contd. • Data base status • Missing data / variablesThe 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. • 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. Knud Thomsen 23 Feb 2007 CSA Information Workshop

  14. Example (2) Molecular DB’s Juelich • Data base access • Internet access Yes • Electronic form (PDF’s) and DB (Hydkin) • Public access • Free • Data base use • Documentation – No not really • User manual – Only for Eirene code • Data base tools - Yes • Data base interface – Yes but basic Knud Thomsen 23 Feb 2007 CSA Information Workshop

  15. Example (2) Molecular DB’s Juelich contd. • Data base status • Range of data – 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, ….) • 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). • Other shortcomings???? Knud Thomsen 23 Feb 2007 CSA Information Workshop

  16. Example (3) Mat-DB JRC Petten • Data base access • Internet access Yes • Rrelational database • Restricted access – Need to register • Free • Data base use • Documentation – Not really • User manual – Not really • Data base tools - Yes • Data base interface - ?? Needs improvement • Data base status • Range of data – gaps?Essential gaps to be filled in the future are properties of joints, low cycle fatigue data and mechanical properties of irradiated materials. • Missing data / variables • Other shortcomingsENEA-RFX has compiled a long list that may be relevant Knud Thomsen 23 Feb 2007 CSA Information Workshop

  17. Example (4) Nuclear Data Services (JEFF, EAF, IEAF) • Data base access • Internet access Yes • Relational database • Public • Free • Data base use • Documentation - yes • User manual - yes • Data base tools - yes • Data base interface - ?? Knud Thomsen 23 Feb 2007 CSA Information Workshop

  18. Example (4) Nuclear Data Services (JEFF, EAF, IEAF)contd. • Data base status • Range of data – gaps? – None at present • Missing data / variables – None at present • Other shortcomingsTo 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. Knud Thomsen 23 Feb 2007 CSA Information Workshop

  19. Example (5) Atomic and Plasma-Material Interaction Data for Fusion (APID ) • Data base access • Internet access Yes • Paper and Relational database • Public access • Free / subscription for paper (not available on web)| • Data base use • Documentation – restricted access • User manual – restricted access • Data base tools - Yes • Data base interface – Not really Knud Thomsen 23 Feb 2007 CSA Information Workshop

  20. Example (5) Atomic and Plasma-Material Interaction Data for Fusion (APID )contd • Data base status • Range of data – gaps?Plasma surface interaction data: Hydride + Wall -> ???Recycling coefficients for atomic and molecular hydrogen isotopes.Sputtering coefficients for H_xC_y hydrocarbons and its isotopes. • Missing data / variables • Other shortcomingsA more recent and widely accessible data base on "Particle Interaction with Fusion Relevant Surfaces" covering physical sputtering, chemical sputtering, reflection, fragmentation/ dissociation, electron emission, implantation, retention etc. would be desirable Knud Thomsen 23 Feb 2007 CSA Information Workshop

  23. ITPA International Diagnostic Database(T. Donne) Many EU devices are underrepresented (JET, FTU, TCV, TJ-II, ISTTOK, etc.). It would be good if those devices could be more active in the IDD. STATUS of IDD today Knud Thomsen 23 Feb 2007 CSA Information Workshop
