The Atomic and Molecular Data Unit is dedicated to continuing to improve the level of access to quality data for use in nuclear fusion energy research. To meet this goal, the Unit will regularly add new features and capabilities to the Unit web server.
XSAMS, XML Schema for Atoms, Molecules and Solids 22 September 2009
The first version (v.0.1) of XSAMS has been released.
The goal of the XSAMS project is to develop a new XML-based standard for exchange of atomic,
molecular and particle-solid(surface)-interaction (AM/PSI) data.
This approach allows one to describe both the static properties of the AM/PSI constituents
and interactions among them in a consistent and well-structured way.
Code Center Network 30 July 2009
The CCN, coordinated by the IAEA A+M Data Unit,
is a joint effort to gather and provide access to any information
relevant for modelers in fusion plasma science.
Its purpose is to provide solutions to anyone willing atomic or molecular
and particle surface interaction (AM/PSI) data which can not be easily accessed
on the web or which simply do not exist.
ALADDIN version 3.2.0 15 July 2009
This is a major upgrade for the Particle Surface Interactions (PSI).
The PSI database has been reviewed and a large amount of new data has been added.
Both web interfaces, for collisional and PSI data, present now the same interface:
ALADDIN version 3.1.1 17 March 2008
This new release fixes a few bugs when user parameters are passed to some fit
functions. Data and fit functions from the following publications have been reviewed:
ALADDIN version 3.1 8 January 2008
In this version, data outputs are displayed in a new window and some new
functionalities are available like a "select all data" button.
The bug on the automatic set of the upper and lower limits,
while selecting and unselecting data is solved.
The exact values of the fit parameters for the fit functions are displayed,
as in some cases rounded values could give incorrect results. Full reference is listed with the
numerical data.
GENIE version 2.3 4 September 2007
The review of the "surface interactions data" is in progress; the web interface is still in its version 2.3.
GENIE version 2.2 23 Janvier 2007
ALADDIN version 3.0 20 July 2006
The numerical database ALADDIN, in its new version 3.0, has an entirely redesigned interface.
Searches are performed more efficiently by using any possible search criteria combinations along with
a filtering function that allows the user to get a better inside view of the database content.
When possible all requested data are displayed in the same units to permit easy comparison.
A unit conversion tool is available and all results can be displayed in tabular and graphical mode.
To implement version 3.0, all data from ALADDIN have been reviewed. This work is complete for the
"atomic and molecular data". The review of the "surface interactions data" is in progress.
GENIE version 2.1 22 April 2005
Two new databases from the Institute of Applied Physics and Computational Mathematics of China (IAPCM)
CAMDB have been introduced in this version:
AMBDAS version 3.0 16 February 2005
In this version the structure of the database has been modified. This allows more efficient searches for
iso-electronic series and for surface interactions. The request symetry problem when specifying two reactants
has been resolved.
New ALADDIN Version 29 November 2004
This new version of ALADDIN includes a large amount of new data. The structure of the database has been
revised to merge and to redistribute the data of the 4 former databases (Collisional Database, H-Beam Neutral
Database, Particle-Surface Database, Elementary Processes in H-He Plasmas) into 2 databases:
Los Alamos atomic physics codes 9 July 2004
This is a gateway to LOS ALAMOS Physics codes. An interface is available to run several atomic physics
codes for calculation of atomic structure, electron impact excitation, as well as ionization processes.
Heavy Particle Collisions 10 June 2004
Cross sections for excitation and charge transfer for collisions between hydrogenic targets and bare ions
can be calculated online. Potential users are asked to request a user name and password.
AMBDAS version 2.2 17 March 2004
In this new version search capibilities have been improved. Presentation of data have been slightly
modified for a better reading. The web interface has also been simplified.
Priorities in Data Compilation, Evaluation and Generation for Fusion
Research 21 November 2003
The priorities in data compilation, evaluation and generation for fusion has been reviewed by the last
DCN meeting held in 6-7 October 2003 in the VIENNA IAEA headquaters.
GENIE version 2.0 14 November 2003
In this new version, search technique has been refined with a large speedup in data retrieval. Instead of
sequentially, data retrieval is done simultaneously for each database. For the spectral databases, of a
present amount of 7, the total response time is about 3 times better and only constrained by the slowest
database web site.
The AMODS Spectral Lines Database from the
Korean Atamic Energy Research Institute (KAERI) has been added.
New Server October 2003
On the 3, November 2003, our website switched on a new server,
a Compaq server running under Linux, Redhat 9.0.
AMBDAS
In the past the bibliographic data used in producing this Bulletin were accessible only through a
Telnet connection. Recently Y. Ralchenko has worked with the Unit as a consultant and produced a
web based interface for the bibliographic database. This allows users to search the entire
bibliographic database using a number of criteria, such as author, process, reactants, etc.
Online Computing
In some cases there are needs for data which are not available in any on-line database.
In that case it is often possible that such data could be calculated from existing computer codes,
so that at least an estimate of the data would be available. The A+M Unit has been working on making
a method for providing access to some A+M codes. J. Peek brought a version of a code for electron
impact excitation cross section calculations to the Unit. This code uses the atomic structure
calculations of R.D. Cowan. These codes have now been made accessible through our webserver,
so that it is possible to calculate approximate cross sections for arbitrary ions for most elements.
GENIE
As new databases become available on-line at various locations, new data relevant to fusion research
have the potential to be accessed. However, to make use of different databases it is necessary for
the user to understand the protocol for each database. In some cases it is necessary to register on
the database as well. In response to this situation the A+M Unit has worked with consultants
Y. Ralchenko and D. Humbert to develop a prototype search engine, called GENIE. GENIE makes it
possible for a user to enter one request for data, either radiative or collisional, and to have that
request sent in proper format to several available databases. Results of the searches are then
presented to the user. Currently this prototype is limited to a few databases and the requests are
quite limited in nature. However, continued development is foreseen and this promises to be a useful
tool.
New data
Considerable new data are constantly being added to the on-line databases. Recently a large amount
of data for plasma-surface interaction has been added. Recently, a large amount of data for
radiated power from plasmas of interest to fusion were made available.
