OPEN-ADAS—

The first twelve months

Overview of ADAS

• The ADAS Project is a self-funding (i.e. funded by participants) projectconsisting of most major fusion laboratories along with other astrophysical anduniversity groups. In its present incarnation it is over ten years old but theroots in JET go back twenty years.

• As an implementation, it is an interconnected set of computer codes and datacollections for modelling the radiating properties of ions and atoms in plasmas.

• Historical roots are in fusion (JET) and so are the bulk of the users/members.Has also been extensively applied to astrophysics.

• Is governed by a steering committee coming from its members. Day to dayrunning and implementation is done by the University of Strathclyde.

Schematic of ADAS Organisation



Size and Scope of use

• Rough idea of the computational ‘size’ of ADAS:

– 3.0GB of data in 20,103 distinct files,– 425,253 lines of Fortran and 406,225 lines of IDL,– also contains C, Perl, csh, Matlab and C++ code,– tentative plans to expand to support Python.

• Used extensively in spectroscopic fusion diagnostic analysis.

• Integrated into key fusion transport codes

– e.g. Strahl, JETTO, SANCO, CHEAP, EDGE2D, B2-IRENE, ERO etc.

• The Project currently has 28 members across the world.



What does ADAS do?

← Universities

Fusion labs→

← ADAS→understands both of

these groups!



Yes, but what does it actually do?

• ADAS, as a computer system, is designed to:

– provide codes which are easy to use,– provide subroutine libraries for inclusion in other codes,– allow direct access to diagnostically relevant data.

• ADAS, as an organisation:

– provides guidance (training courses, visits etc.) on running codes,– gives recommendation on the best data to use,– assists in analysis and development of analysis tools and models.

ADAS brings people (diagnosticians, modellers and atomic physicists)together on the topic of atomic physics for magnetically confined fusion.



Parts of ADAS

• Interactive ADAS

• The ADAS database

• Extended ADAS

• ADAS subroutine library

• ADAS Documentation (over 4000 pages!)

• Extended ADAS

• OPEN-ADAS

http://www.adas.ac.uk



OPEN-ADAS

• OPEN-ADAS is a joint development between the IAEA and the ADAS Project.

• Main goals are:

– to index the data contained within the ADAS database,– to provide a searching system for these data,– to re-work the documentation and data status,– to provide access to the data freely via the web.

• With the exception of the last point, all of the above have benefit to ADASProject members.

• Primary goal, from the point of view of non-ADAS members is to disseminatekey data to a wider user base.



Scope of OPEN-ADAS

• OPEN-ADAS is limited to a selection of key data classes:

– key diagnostic data classes for fusion are targeted,– opacity (and related data) already available,– no point in releasing driver files.

• OPEN-ADAS does not release any of the ADAS code, only data,

– exception is code necessary for reading the data.

• New developments with flexible partitioning will not be included:

– still in development (not yet fully released with ADAS),– need to be tuned to transport characteristics etc.,– best used with close support from ADAS personnel.

The first twelve months

• OPEN-ADAS was launched at the end of July 2009.

• Seamless upgrade from ADAS Database v2.12 to v2.13 in October 2008.

• Statistics in this talk are based from 1st August 2008 – 1st August 2009.

• Since launch almost 100% server uptime (two power cuts).

• Daily usage report is automatically generated every morning.

• Some feedback but no complaints or bugs with the system.

Signups

• In order to download data, (free) registration is required.

• As of 1st August 2009 (twelve months since launch):

– 124 registered users,– 35 from ADAS member institutions,– 89 from non-ADAS member institutions.

• Following statistical breakdowns are based on above but as of Friday there hadbeen an additional eleven registrations.

Did OPEN-ADAS meet expectations?

• Around 70% of users are from non-ADAS member institutions.

• Good geographical spread of users.

• Steady stream of people registering with the site.

• User interest is focussed on atomic physics, databases and fusion.

• Freeform search is well used.

• Fundamental data in ADF04 files is being distributed more widely.

• Derived data, especially ADF11 and ADF15 are being downloaded.



Conclusions

• Talk covered:

– background aspects of ADAS,– scope and design of OPEN-ADAS,– usage of OPEN-ADAS in the first twelve months.

• The ADAS database is not the only part of ADAS but it is arguably the mostimportant and certainly core to everything which ADAS does. OPEN-ADAS isallowing free access to this database.

• We think that our database complements rather than competes with otheratomic physics databases.

• As such, ADAS would like to join the DCN as an official member.
