Kovalchuk Boris (April 10th. 1940 Magnitogorsk, Chelyabinsk region) -dokt. tehn. Sciences, Academician of the Russian Academy of Sciences.
Graduated high school in 1957, he entered the EEF in TPI, which he graduated in 1962 with a degree in "Electrical networks and systems". In a review of his thesis it was noted that B. Kovalchuk did a great experimental work has shown himself a creative worker, able to apply their knowledge in practice. Like other talented graduates, Boris Kovalchuk was left in the TPI in the Institute of BH. For four years he worked at the Institute of BH and the Institute of Nuclear Physics engineer, engaged in experimental activities. His achievements are summarized in scientific articles. One of them was published in 1963 in Technical Physics. In the nanosecond pulse generator was set this time they are mastered oscilloscopes, measurement methods, etc.
This work was pioneering. Boris began to work in the group GA Month and engaged in the creation of high-voltage nanosecond technology. The first user of this technique was the All-Union Electrotechnical Institute named. Lenin, the laboratory of prof. Granovsky, the famous scientist, the author of many books on physics of plasma gas discharge. In 1966 Boris Kovalchuk enrolled in graduate school at the TPI, which he graduated in 1969 with a PhD defense. diss. on the theme "Development and research of generators nano-second high current pulse." Recalls Acad. GA Month worked with Boris Kovalchuk, the success of the young scientist was so great that sometimes it leads to some oddities. For example, in 1968 work group GA Months were exhibited at the Lenin Komsomol Prize in Science and Technology. Among the four authors were and Boris Kovalchuk. GA A month has already been Doctor. Sciences, S. and V. Bugaev Kremnev - Cand. Sciences and Boris Kovalchuk - graduate student. The expert commission in Moscow, suggested deleting a graduate student, so as not to spoil the overall picture, but the contribution to the work of Boris Mikhailovich was so significant that his co-authors did not agree with the findings of the commission. GA Month defended the rights of BM Kovalchuk. In the early 70`s Boris worked at the Institute of Atmospheric Optics SB RAS in the position of the head. of Lab. nanosecond technology. As of Lab. was transferred to the ISE and Russian Academy of Sciences of the USSR was reorganized into the department, he was its leader. ISE in cooperation with the TPU becomes one of the leading centers of high-current accelerators. His first director was GA Month and 1985 SP Bugaev. Worked here Member of RAS Yu Kotov, VG Shpak, prof. DI. Proskurovsky, JE Kreindel, PM Schanin et al.
The range of scientific interests BM Kovalchuk is quite wide, and the ideas that he proposed in the experimental work, is the most successful and bring tangible results. Thus, the accelerator with a current of 10 kA and an electron energy of 500 keV was established in 1967. It was the first accelerator in the USSR. Later, his interest focused on large switching pulse shackles and generation of powerful high-voltage pulses. In 1979 he defended his Doctor. diss. on the theme: "Issues of switching to high-voltage nanosecond pulsed high power devices." Boris worked to develop power for heavy-duty lasers. Thanks to his efforts created unique while POPs lasers LAD-1, LAD-2. Last radiation with an energy of 5 kJ pulse duration of 500 nanoseconds still rabotaetv in-those of General Physics in Moscow. The largest development B. Kovalchuk is a system of high-power devices to the relativistic high-frequency electronics. He developed a quick generators ry Marx, providing them parallel. This setup was unique in the world. Thanks to the brilliant design of the system worked very well. BM Kovalchuk has decided the problem of transition from plasma-breakers, which converts the pulses with a duration of hundreds of nanoseconds to tens of nanoseconds to converters microsecond current current duration of hundreds of nanoseconds. They idea of energy transfer has been used from the Marx generator in the vacuum line accumulative Plasma breaker. This work was brilliant and caused a rapid interest in the world, after the conference papers in Japan and the United States.
Among implemented under his leadership and with his direct participation projects, the pulse generator terawatt plasma opening switch HIT-16 was included in the list of unique research facilities in Russia. In recent years, he and his colleagues developed a fundamentally new element base for creating a pulsed-power plants on the basis of terawatt power generators Arkadieva-Marx and linear pulse transformers. These works are carried out in close cooperation with foreign colleagues from Sandia National Laboratory (USA) and the Research Center in Gram (France).
Boris Mikhailovich small research team, in which all are working very hard, as a team of like-minded people. BM Kovalchuk - the world-famous scientist. He is a regular participant in international conferences on high-power electron beams, for high-power pulsed technology, for high-current electronics, author of over 200 scientific works and inventions. In 1997 the American Institute of Electrical Engineers and electronics engineers (IEEE) awarded him the International Prize named Erwin Marx, awarded every two years to only one scientist in the world for outstanding work in the field of pulsed power.
According to colleagues, Boris is very unusual person, totally unselfish, always trying to help all, never seeks to ensure that the show itself. For him, in science the result is important. He has many disciples, followers. He works all the time, running his hands, conducting experiments, participate in the construction. As pointed out by GA Month, "BM Kovalchuk - a very special academician! And that science has established them - high-current electronics and pulsed electro physics, despite the current difficulties, did not die, of course, the merit of such people as Boris Kovalchuk. I am proud to be standing at the beginnings of his scientific career. "
Work BM Kovalchuk with awards: Lenin Komsomol in the field of science and technology (1968); USSR State Prize (1968); State Prize of the Russian Federation (1998) and the International Prize. Erwin Marx (1997);
Honours: Order of Friendship of Peoples (1986); Order of Merit (1997).
