Republic of Bulgaria

General information on collaboration

The Republic of Bulgaria (before 1992 the People’s Republic of Bulgaria) was a JINR Member State since its foundation in accordance with the Agreement signed on 26 March 1956 in Moscow. At the ceremony of signing the agreement, the People’s Republic of Bulgaria was represented by PRB Ambassador Extraordinary and Plenipotentiary in USSR Doctor Luben Nikilov Gerasimov who was authorised to sign the Charter of JINR.

Nowadays, the Republic of Bulgaria is one of the most active JINR Member States in terms of participation in JINR activities, number of joint projects and number of scientific and technical contacts. 26 Bulgarian experts are currently working at JINR. Most scientists participating in joint projects conduct research in Bulgarian universities and in institutes of the Academy of Sciences of Bulgaria applying techniques and methodology developed at JINR. Bulgarian researchers make short-term business trips to Dubna.

High proficiency of Bulgarian experts allows them to be in high-level positions within JINR scientific teams. Academician Ch. Christov (1968-1970), professor I. Zlatev (1979-1983) and professor C. Vilov (1992-2005) were elected as JINR Vice-Directors. Hundreds of Bulgarian scientists have worked at JINR and received good training in Dubna laboratories. Today, they are the core of Bulgarian nuclear physics.

Cooperation exists in all fields of JINR activities. However, high priority areas are elementary particle physics and relativistic nuclear physics. Research topics of the Veksler and Baldin Laboratory of High Energy Physics, the Dzhelepov Laboratory of Nuclear Problems, and the Bogoliubov Laboratory of Theoretical Physics are the most interesting for Bulgarian scientists. In recent years, radiation and radiobiological research have attracted Bulgarian scientists, and thus they take an active part in research on these fields.

JINR conferences have been held in Bulgaria for several years. Some of them have become regular (such as the International Symposium on Nuclear Electronics & Computing (NEC) held in Varna every two years).

National groups

The languages of international communication at JINR are Russian and English. However, one can hear the speech in many languages in Dubna, including the languages of JINR member-states when the countrymen, the representatives of the same expatriates’ community (the national groups of JINR), meet each other.

Over the years of existence of JINR the national groups have developed their traditions, forms of cooperation and collaboration with other national groups. Their leaders, appointed by the plenipotentiaries of the JINR member-states play an organizing role in the life of national groups.

  • Professor Fiziev Plamen Petkov
    Head of the national group of Bulgaria, Leading Scientific Reseacher, BLTP JINR

  • +7 (496) 216-35-62

  • dimov@theor.jinr.ru

  • Dabrowska Boiana Rumenova
    Deputy Head of the national group of Bulgaria, reseacher, VBLHEP JINR

  • +7 (496) 216-38-71

  • boiana_marinova@abv.bg

Being in constant contact with plenipotentiaries, embassies of member-states, JINR’s directorate and management services, they take part in the solution of the problems connected with the stay of their colleagues-countrymen and their families in Russia, with the organization of their life and leisure.

The Council of the leaders of the national groups meets periodically. The representatives of the Directorate and the services of the Institute are invited to its meetings. The agenda includes the discussion of the urgent problems of the collaborators from the member-states. Due to this, the Directorate is able to make adequate decisions in time.

On the occasions of major public holidays of the member-states the national groups arrange receptions. These festive events are held accompanied by art exhibitions, photo exhibitions, and enrich JINR staff members’ knowledge about the member-states, their people and culture.
