Database of Ion Beam, Spallation Neutron and Synchrotron Light Sources in the World


The Database of Ion Beam, Spallation Neutron Sources and Synchrotron Light Sources in the World contains technical information on accelerator-based radiation facilities used for applied research and analytical services in IAEA Member States. The database is compiled using information publicly available from IAEA databases, research institutes in Member States and accelerator manufacturers. The IAEA makes no warranties, either express or implied, concerning the accuracy, completeness, reliability, or suitability of the information.

The database organises the accelerator-based radiation facilities into three categories: low-energy electrostatic (ion beam) accelerators, spallation neutron sources and synchrotron light sources. Included are geographical maps of the global distribution of these facilities and as well as individual entries in Member States.


There are 163 entries for low-energy electrostatic accelerators distributed over 50 Member States. These accelerators are sub-divided into 4 categories: EN-FN-MP-UD, Pelletron®, single-ended and Tandetron™, representing the wide variety of machine technologies in use today both modern and old.

There are 9 entries for spallation neutron sources distributed over 5 Member States and 38 entries for synchrotron light sources distributed over 20 Member States.

The IAEA plays an important role in helping to establish sound frameworks for the efficient, safe and secure use of nuclear technologies, and to develop the capabilities and infrastructure of interested Member States to manage their own programmes devoted to nuclear and radiological applications. This database provides Member States with a resource to assist efforts in developing strategies for capacity building, and effective utilization and management of research facilities on a national, regional and international basis through possible coalitions, networks and shared-user facilities.

The IAEA wishes to thank Christian Nuviadenu of the Ghana Atomic Energy Commission, Ghana, for creating and compiling the database. The IAEA officer responsible for the production of the database was Nikolai Dytlewski of the Division of Physical and Chemical Sciences.
