Nikolai Timofeevich Cherpak was born on December 19th 1939, in the city of Novomoskovsk, Dnipropetrovsk region. After finishing seven classes of secondary school, he went to study at the Dnepropetrovsk Industrial College, in which he acquired skills in the specialty "Metallurgical Production" in 1958. He began his career at the Dnipro's Metallurgical Factory in name of F.E. Dzerzhinsky as a technician of the brigade of the blast furnace technological workshop. However, soon the stubborn pursuit and the craving for knowledge did not allow to retreat, so in 1960 he entered the Leningrad Polytechnic Institute in name of M. Kalinin at the Faculty of Radio Electronics, and in 1966 he graduated with honors in the specialty "Radio Physics and Electronics". Learning in university classes and research work at the department while studying at the Institute, led to determine the direction of further scientific research. In 1966, N. T. Cherpak, according to the distribution, joined the IRE of the Academy of Sciences of Ukraine. In the same year, he was accepted to the graduate school where he continued his research activities, developing and studying quantum para-magnetic amplifiers (CPUs) of the centimeter range. The results of research in the field of quantum Radio-physics formed the basis of his Ph.D. thesis, which was successfully defended in 1970. A constant attracting scientific search, accompanied by new scientific discoveries, with a group led by him, allowed N.T. Cherpak to discover, investigate and develop a CPU of a traveling wave of the millimeter wavelength range with a wide gain band, which was successfully tested in Nizhny Novgorod on RT- 25x2 radio telescope. The data obtained from the results of the tests formed the basis of the Doctoral dissertation, he successfully defended the second in 1987. N.T. Cherpak became the pioneer of a new direction in the research of high-temperature superconductivity (HTSC), which was the beginning of a new scientific activity of the IRE Academy of Sciences of Ukraine. Continuous painstaking work in this direction has brought important results that have been recognized both in Ukraine and far abroad. Thanks to the presented experiments and works, in 1999 N.T. Cherpak was awarded the title of professor, and for a large cycle of research work in the field of microwave electrodynamics of HTSC, together with his colleagues, the Presidium of the NAS of Ukraine awarded them a prize in name of I. Pulyuya in the field of experimental physics. In 2013, a scholarship was awarded to the Kharkiv Regional State Administration in the field of physics and astronomy in name of K.D. Sinelnikov for outstanding scientists. Also, in 2015, a prize was awarded to him in name of L.V. Shubnikova for unique scientific work in the field of experimental physics, namely in the direction of low-temperature physics. Currently, N.T. Cherpak and his group continue research in the field of microwave properties of HTSC. In particular, the creation and application of electrodynamics models of microwave structures are studied in more detail, intended both for using the HTSCs themselves and for use in various radio-physical systems. Numerous successfully solved problems were solved in a fruitful and close collaboration with scientists from China, Great Britain, Germany, the USA, and others. During his work at the IRE of the Academy of Sciences of Ukraine, N.T. Cherpak in collaboration with colleagues, more than 400 scientific papers were published in domestic and foreign magazines, received more than 20 unique copyright certificates and patents for inventions, including two patents in conjunction with the United States. Nikolai Timofeevich - author of the monograph “Quantum Paramagnetic Distributed Amplifiers in the Millimeter Wave Range” (1996), co-author of the monograph “Quasi-Optical Solid-State Resonators” (2008) and the Russian-Ukrainian Dictionary of Radio Engineering, Radio Electronics and Radio Physics (2006). N.T. Cherpak devotes most of his time to teaching and upbringing in the special course "Low-Temperature Electronics" at universities such as KNTU "KhPI" and KNURE. He is a member of the academic council of the Institute, a specialized council for the defense of dissertations in KNURE. Under his strict guidance, dissertations of seven people were prepared and presented, which successfully continue to develop scientific activities at the institute and abroad (Great Britain, China, Germany, Italy, Portugal). N.T. Cherpak is an active participant in international scientific forums, a member of the scientific societies IEEE and ESAS, a member of the program committee of EuMC, EuMA, and MSMW.
