University of Latvia's Institute of Solid State Physics (ISSP) is the EUROfusion partner representing Latvia's fusion research initiatives. The Latvian contribution to the European fusion programme began in 2000 in the form of cost-sharing actions and the Association EURATOM-University of Latvia was established in 2001.
Fusion researchers from ISSP focus on exploration of radiation and heat-resistant ODS (oxide dispersion strengthened) steels that are used in fusion reactors.
Research on ODS steels
ISSP has coordinated and collaborated with another EUROfusion members, Karlsruhe Institute of Technology (KIT, Germany) and CEIT-IK4 (Spain), in a EUROfusion project aimed at better understanding formation of oxide nanoparticles in the ODS steels. X-ray absorption spectroscopy measurements have been carried out at international synchrotron radiation facilities for ODS steels samples, produced by KIT, CEIT-IK4, and for model materials produced in ISSP. The aim is to obtain unique information regarding local structure of atoms in oxide nanoparticles in ODS materials and to find when and how oxide nanoparticles are formed.
In parallel kinetic Monte-Carlo modelling of oxide nanoparticle formation and growth is performed and supporting ab initio calculations of Y-O clusters and defects in iron matrix are accomplished. This model will be validated with X-ray absorption spectroscopy and other experimental data.
EUROfusion Enabling Research Project "When and how ODS particles are formed? - X-ray Absorption Spectroscopy and ab initio modelling of ODS steels", (CfP-WP15-ENR-01/UL-01), 2015-2017 (Head: Dr. habil.phys. J. Purans, Institute of Solid State Physics, University of Latvia).
R&D contribution for gyrotron development
ISSP is also involved as a Third Party in the research and development work related to gyrotrons. The European Domestic Agency is responsible for six of the 24 gyrotrons that will be installed in ITER. ISSP along with KIT (Germany), SPC (Switzerland), HELLAS (Greece), CNR (Italy), University of Stuttgart (Germany), and Thales Electron Devices (France) are collaborating in the gyrotron development work for ITER.
