Cooperation and international projects

In 2008, the A.Ya. Usikov IRE and Korea Electrotechnology Research Institute (KERI) (Ansan-city, Republic of Korea) have signed a contract for the development of a 35 GHz low-voltage pulsed magnetron. In course of the contractual works, the Principal Researcher from the Korean party Dr. Jung-Il Kim and the Director of Center for Pioneering Medical-Physics Research at KERI Dr. Jong-Uk Kim visited the Institute. One of the outcomes of this visit was signing of a Memorandum of further cooperation between our institutes in the area of vacuum electronics.

In 2011, the second contract was concluded with the Korea Electrotechnology Research Institute (KERI) which goal was to develop a 100 GHz clinotron-type electromagnetic oscillator of the continuous-wave output power of 10 W. During the contract time the project leader from Korean party Dr. Jung-Il Kim visited the Institute again to personally accept the R&D output.

In 2013, on a working visit arrived Prof. Toshitaka Idehara, the Honorary Director and Manager of international projects at the Research Center for Development of Far-Infrared Region, University of Fukui (Japan), and Prof. Masahiko Tani, the Director of the Research Center for Development of Far-Infrared Region, University of Fukui. This visit ended with signing of a Memorandum of joint research and development in the far-infrared region.

The investigation and development of 460 GHz middle power gyrotrons with an enhanced frequency stabilization for DNP/NMR spectroscopy have been performed with the participation of Japanese colleagues Prof. T. Idehara, Prof. M. Tani and Prof. T. Saito, as well as the research team headed by Prof. T. Fujiwara from the Institute for Protein Research, Osaka University (Japan).

During the last years the Department closely collaborates with the Institute of Applied Physics of Russian Academy of Sciences (Nizhniy Novgorod, Russian). Two projects for young scientists sponsored by the Russian Foundation of Fundamental Research have been successfully accomplished by the joint efforts of Ukrainian researchers A. Kuleshov, PhD, and S.A. Kishko, a research scientist, and their Russian colleagues Dr. M.Yu. Glyavin, Senior Scientist, I.V. Zotova, PhD, Senior Scientist, Prof. N.S. Ginzburg, and M.I. Petelin, Senior Scientist. The outcome of this collaboration was a planar gyrotron with a transverse-longitudinal direct energy output.

Prof. I. Alexeff from the University of Tennessee, Knoxville, USA took an active part in the discussion and analysis of the results of an experimental research on low-voltage operation modes of nuclear-magnetic resonance and theoretical study of the “optional” mechanism of electron bunching in a low-voltage CRM due to a weak inhomogeneity of the magnetic field in the resonator area of the gyrotron.

Some of the results obtained in the framework of the international research projects are reflected in the following publications.

 In 2011, our guest was the founder of the Nuclear and Plasma Sciences Society of IEEE Prof. Igor Alexeff from the University of Tennessee, Knoxville, USA.

In 2011, we for the first time invited a team of leading experts of the Eastern China R&D Institute “Photoelectronics” headed by the Chief Engineer Dr. He Giaochan, and already in 2012 a representative delegation in the lead of the Director of this institute Mr. U Huasya arrived to sign a long-term joint R&D contract.

In the last decade, our scientists also have travelled abroad a lot to establish important business relations.

In 2010, A.S. Tishchenko and V.A. Goryashko visited the Korea Electrotechnology Research Institute (KERI) in Ansan-city (Republic of Korea) to get familiar with the achievements of the Korean colleagues and to deliver the accomplished contractual words.

In early 2012, a delegacy of IRE scientists including V.D. Yeryomka, V.S. Miroshnichenko, A.Ye. Kogut and A.S. Tishchenko visited the Eastern China R&D Institute “Photoelectronics” in Wuhu city (PRC) to negotiate the contract for joint investigation and development of the clinotron-type sources.

The vigorous international activity of A. Kuleshov, Senior Scientist, has a broad geography and wide field of interests:

in 2008 he visited the Karlsruhe Institute of Technology, Germany, where he came up with a proposal of joint development of portable gyrotrons and clinotrons for various real-life applications;

in 2009 his destination was Canada, the Department of Foreign Affairs and International Trade; the goal of the trip was to attract customers and partners for the development of electromagnetic radiation source in a wide range from microwaves to X-ray radiation. Next goal:
