Leo K. Kovalev, 1941 - 2014, Remembered
February 7, 2014 (PO26). On January 28, 2014, Prof. Leo K. Kovalev suddenly passed away in Moscow from a myocardial infarction at the age of 72. To the superconducting electro-machinery community, Leo K. Kovalev was well known worldwide through his work on electric machines with HTS bulk elements, comprising hysteresis motors, reluctance motors and motors utilizing permanent magnets. He also paid great attention to HTS-magnetic-suspension systems for high-speed rail-borne transportation and flywheels.
In 1964, he started his professional career at the Central Institute of Aircraft Engines, Moscow, after graduating from Moscow State Technical University Named After N. E. Bauman. A few years later he joined the Department of Electric Machines, the Dept. 310, of the Moscow Aviation Institute (MAI), headed by Prof. Albert I. Bertinov. During that time he pursued research in the field of MHD (magneto-hydrodynamic) energy conversion, and in 1972 he finished his Science Candidate (doctoral) dissertation on MHD generators. For the following ten years his research activity shifted to ionosphere radio physics, hydrodynamics and radio waves propagation at the Scientific Research Institute of Long-Haul Radio. During 1980-1982 he was the Deputy General Constructor of that institute. In 1982 he returned to the Dept.310 of MAI, headed at that time by Prof. Dmitry A. But, and continued research on MHD problems and in parallel extended his interest to low-temperature superconducting electric machines. When In 1986, when high-temperature superconductivity (HTS) was discovered, Leo concentrated his research on HTS electric machines and developed several series of cryogenic electric machines utilizing bulk HTS elements, operating at liquid nitrogen temperatures. He is the author of four books and more than 200 scientific and technical papers. In 1996 he attained his D.Sc. (habilitation equivalent) degree and became a Professor. Since 2002 he headed Dept. 310 of MAI, and in that same year he was awarded the State Prize of Russian Government in the field of Science and Technology. He initiated “The Centre of Superconducting Electric Machines and Devices” at MAI. Leo was an enthusiastic specialist in electromechanics, applied superconductivity, hydrodynamics and radio physics. He liked to first identify new scientific problems and then to solve them.
He actively took part in the international development of superconducting electric machines and was one of the initiators of the German-Russian cooperation, leading to the design and development of superconducting electric motors with liquid nitrogen cooling. The consortium comprised: Oswald Elektromotoren GmbH (Miltenberg), Stuttgart Technical University, IPHT (Jena), IFW (Dresden), Moscow Aviation Institute, A.A. Bochvar All-Russian Scientific Research Institute for Inorganic Materials (Moscow), All-Russian Electrotechnical Institute (Moscow), and the Institute for Solid State Physics (Chernogolovka, Moscow region).
Prof. Leo K. Kovalev was an Academician of the Russian Academy of Electrotechnical Sciences, an Honored Scientist of Russian Federation (RF), and an advisory council member of Highest Certifying Commission (RF).
Besides his research activities, Leo K. Kovalev was a true intellectual and a real friend for all his partners. Everyone who visited his Moscow home or countryside residence was surrounded with hospitality and warmth. He possessed a rare gift of charming his interlocutor from the very first words of communication. He left behind his dear wife Tatiana and a son, who like all of us will miss him very much.

Alex Shikov Unexpectedly Passed Away
October 30, 2013 (PO22). Professor Alex Shikov unexpectedly passed away on October 26, 2013. Alexander Konstantinovich Shikov was born in Norilsk (then USSR) in 1948. He graduated from the Moscow Steel and Alloys Institute in 1971 and started his scientific career as a junior research associate at the Bochvar Institute of Inorganic Materials, also in 1971. He received his D.Sc. (Habilitation) degree in 1991. Since 1998, Dr. Shikov served as the deputy director of Bochvar Institute, and from March to August 2009 as its Head. He was then appointed as the Executive Director of Kurchatov Institute's center for Nano-Bio-Info-Cognitive (NBIC) Science and Technology. Memorial ceremonies were held on October 30, 2013, in Kurchatov Culture Center.
Shikov made an outstanding contribution to restoration of production of superconducting materials after the collapse of Soviet Union. Due to his scientific and management talents, Russian conductors for ITER are today competitive or even exceed the highest performance requirements. While at Kurchatov Institute, he directed research into superconducting materials for ITER and initiated production of HTS materials. Prof. Shikov was an author of three monographs, 250 papers in peer-reviewed scientific journals and 60 patents. He held a Chair of the Applied Superconductivity division in the Moscow Institute of Engineering Physics (Moscow’s outstanding Technical University).
Prof. Shikov was awarded several State Prizes in the field of science and engineering, an award of the Russian Academy of Sciences, the gold and silver medals of the International Exhibition of Inventions. He was a member of the Academy of Electro-technical Sciences of the Russian Federation. He also received an International Cryogenic Materials Conference Best Paper Award at the meeting in Tucson, Arizona in July 2009.
The memory about this outstanding man will be carried not only by his conductors with non-decaying currents and will last. All who knew him will remember his energy, motivation, optimism and achievements.
