From 21 to 28 June 2026, Yerevan and Jermuk (Armenia) hosted the ASRP–BRIA 2026 combining the fifth Alpic School for Radiation Physics and the tenth Beam & Radiation Interaction and Applications conference. FLAP Collaboration representatives who conduct research on the main JINR facilities actively participated in the international forum.
The international FLAP (Fundamental & Applied Linear Accelerator Physics) Collaboration includes researchers from Armenia, Belarus, Chile, China, Great Britain, and Russia. Its main objectives are studying electromagnetic interactions and particle generation processes, developing diagnostic methods for relativistic electron beams, and searching for new applications of controlled electromagnetic irradiation created by relativistic electrons using functional materials. Today, the collaboration members conduct their research using the MT-25 Microtron at the Laboratory of Nuclear Reactions at JINR and the IREN Resonance Neutron Source at the Laboratory of Neutron Physics at JINR.
This year, the event brought together 167 people, including young scientists, students, postgraduate students, and established researchers from Armenia, Russia, Italy, Great Britain, Malaysia, Saudi Arabia, Greece, Turkey, Colombia, and other countries.
The scientific programme consisted of 20 lectures by leading specialists, as well as more than 50 talks and 45 poster presentations. The main topics were:
- beam physics and interaction with matter;
- medical physics and radiation safety;
- archaeometry and cultural heritage preservation;
- materials physics and crystallography;
- acoustics and plasma technologies;
- beam diagnostics and accelerator technology.
Following the results of the ASRP–BRIA 2026 School and Conference, selected articles by the participants will be published in a special issue of the Radiation Physics and Chemistry scientific journal.
Members of the international FLAP Collaboration from Tomsk Polytechnic University (TPU) commented on the results of experiments on the MT-25 Microtron. Sergey Stuchebrov gave a talk titled “Feasibility of 3D-printed targets for coherent Cherenkov diffraction radiation generation”, while Angelina Bulavskaya presented a poster presentation titled “Investigation of Smith-Purcell radiation from high-energy electrons in air and a dielectric medium”. In addition, FLAP Collaboration Press Secretary Pavel Karataev gave a lecture on the properties of coherent Cherenkov diffraction irradiation in the super-radiant mode.
A significant event for the Joint Institute was the announcement of the results of the Best Young Researcher competition held as part of the forum. Among the three laureates was employee of the Scientific and Experimental Department of Theoretical and Methodological Support of Projects at the Laboratory of High Energy Physics at JINR (under the supervision of Anton Baldin), TPU postgraduate student Elizaveta Bushmina. Her talk was dedicated to an experimental study of Cherenkov diffraction irradiation generated by a conical dielectric target on the electron beam of the MT-25 Microtron.
