Their names are in the history of science

Ivan Ts.Ivanov is 80 years old

September 11 marks the anniversary of I.Ts.Ivanov, a famous Bulgarian scientist and engineer that has made a great contribution to Bulgarian science and the scientific fields developed at the Joint Institute for Nuclear Research.

I.Ts.Ivanov was born in the village of Karlukovo in Bulgaria. In 1962, he completed his studies at the gymnasium and entered the Mining and Geological University in Sofia. From 1963 to 1965, he served in the Bulgarian People's Army. In 1970, he graduated from Sofia University with a degree in Atomic Physics. As a student, he made the first laser hologram in Bulgaria and defended his diploma thesis on this topic.

As a holography specialist, I.Ts.Ivanov worked at the Laboratory of Nuclear Problems of JINR from 1976 to 1983. In the Sector headed by Professor Yu.A.Shcherbakov, he designed a number of streamer hydrogen/deuterium chambers at pressures of 2.5 and 10 atm with holographic data acquisition and using a powerful nitrogen laser. His PhD thesis was based on this work.

During his work at JINR, he developed new equipment for tracking data acquisition based on a powerful nitrogen laser. On this basis, a full-scale streamer chamber was constructed that successfully operated at the DLNP cyclotron.

Upon returning to Bulgaria, I.Ts.Ivanov was elected as Head of an international team of scientists from the Institute for Nuclear Research and Nuclear Energy (INRNE) of the Bulgarian Academy of Sciences, JINR, Leningrad Nuclear Physics Institute of the USSR Academy of Sciences and the Technical University of Ilmenau, GDR. In 1985-1989, under his supervision, the team developed a unique holographic streamer chamber at a pressure of up to 50 atm, in which, for the first time in the world, tracking data was accumulated using SSD.

From 1984 to 2014, I.Ts.Ivanov worked at the Institute for Nuclear Research and Nuclear Energy (INRNE) of the Bulgarian Academy of Sciences (BAS), first as a researcher and afterwards, as Head of the Innovation Bureau of the INRNE BAS.

While working at the INRNE BAS, I.Ts.Ivanov implemented a number of large projects, in particular, in collaboration with a number of institutes, he designed a holographic streamer camera with laser-optical registering of track data, operating with hydrogen filling under a pressure of 50 atmospheres. He also developed hardware suite for research at the synchrophasotron and Nuclotron of the High Energy Laboratory. In 1986, I.Ts.Ivanov was awarded the academic degree of Candidate of Physical and Mathematical Sciences. I.Ts.Ivanov took part in the development and preparation of equipment at the European Organization for Nuclear Research and at the German Physics Centre DESY in Hamburg.

At the suggestion of I.Ts.Ivanov and under his coordination, within the framework of cooperation between Bulgarian scientists and scientists from VBLHEP and LRB JINR with funding from the Bulgarian Nuclear Regulatory Agency, a project was developed to study the treatment of melanoma using ion and proton beams of the Serpukhov accelerator and the phasotron of DLNP. The results of the first stage of the project were published. Ivan Ivanov was engaged in pedagogy. Under his supervision and within the framework of the projects supervised by him, 21 diploma theses of Bulgarian, Russian and German students and five PhD theses were defended.

Recently, as a senior researcher and consultant at Advance Solution by Computer Implementation (ASCI Ltd), he has carried out developments intended for the NICA project at JINR.

For a number of significant engineering developments, Ivan Ivanov has been elected a full member of the International Engineering Academy.

I.Ts.Ivanov is a co-author of more than 100 scientific papers published in prestigious physics journals.

Ivan is widely engaged in the popularization of science. He has written a number of articles in the Bulgarian press about the history of the development of holography and the use of particle beams for the treatment of oncological diseases, about global warming and research on thermonuclear fusion. At the same time, he notes the great role of JINR and Russian scientists in these areas.

Ivan has remarkable human qualities, is frank and principled, very responsive, always ready to help. He also has a subtle sense of humor.

We wish Ivan the best of health, new original engineering solutions and family happiness.
