NEWS FROM THE MEMBERS OF THE CONSORTIUM
The 6th International Workshop on Far-Infrared Technologies
2017 (IW-FIRT 2017)
The 6th International Workshop on Far-Infrared Technologies 2017 (IW-FIRT 2017) and the 2nd
International Symposium on Development of High-Power Terahertz Science and technology (DHP-TST2017) organized by the Research Center for Development of Far-Infrared Region has been held
successfully at the University of Fukui from 7th to 9th March, 2017.

Testing the European 1MW/170 GHz gyrotron at KIT-IHM
Excellent results for the European 1 MW gyrotron prototype were reported on 28 February 2017 (visit:
http://fusionforenergy.europa.eu/mediacorner/newsview.aspx?content=1099). It has been developed in acollaboration between the manufacturer – the French company Thales Electron Devices (TED) and theEuropean Gyrotron Consortium (EGYC) as a powerful source for Electron Cyclotron Resonance Heating(ECRH) of fusion plasma in ITER. During testing, the gyrotron (pictured below) repeatedly produced up
to 0.8 MW of output power during periods of 180 seconds – the maximum time possible at the test facility
at Karlsruhe Institute of Technology (KIT). These results have been assessed by an independent expert
panel which concluded that for a first gyrotron prototype, they are impressive.

SHORT PAPER

PERSONALIA
Michail Petelin (on his 80th birthday)

Professor Michael Ivanovich Petelin was born on 7 March 1937 in Nizhniy Novgorod. He graduatedfrom the University of Nizhny Novgorod, Russia, in 1959. He has been employed since then by the
Russian Ministry for Higher Education and the Russian Academy of Sciences, combining theoretical andexperimental research activities with the training of new generations of researchers at the Institute ofApplied Physics, Russian Academy of Science in Nizhny Novgorod and at the Nizhny Novgorod State
University. He has held positions as a visiting professor at the University of California, Davis, Seoul
University, Korea, Institute of Electronics, Chinese Academy of Sciences, Beijing, and the Research
center for Development of Far-Infrared Region at the University of Fukui, Japan..
Prof. M. Petelin has worked since nearly the beginning of his career on the theory and design ofcomponents for high power coherent radiation sources using relativistic electron beams. From 1963 to
1973 he led a team of scientists and engineers that developed the gyrotron. During that period the peak
power achieved in a gyrotron increased from a few watts to 1MW. Gyrotron oscillators are now
commonly used for plasma heating and current drive in magnetic fusion systems. Gyro-amplifiers are usedin long-range high-resolution radar systems. Starting in 1969, jointly with various Russian, American andEuropean teams, Prof Petelin led research to develop gigawatt, nanosecond pulse microwave generators
driven by high-current electron accelerators. In 1996 such a microwave generator was used in the UKRussian research radar NAGIRA. From 1966 Prof. Petelin led the development of quasi-optical wave
transmission and control components, including mode converters, polarizers, pulse compressors, andmultiplexers for matching high power millimeter and microwave sources to various systems. Recently hehelped develop the German-Italian-Russian quasi-optical duplexer FADIS, which is used for combining
powers from two 140 GHz / ~1MW gyrotrons and for fast switching of the combined beam. These
duplexers are designed to help control hot plasmas in fusion experiments.
In 1967 Prof. Petelin was the co-recipient of the State Prize of the USSR for the development of the
gyrotron and in 2003, the State Prize of Russia for the development of pulsed High Power Microwave
generators. In 1996 he was awarded the K. J. Button Prize for his contributions to research on millimeterwaves. In 2011 Professor M. Petelin received the John R. Pierce Award for Excellence in Vacuum
Electronics for “the invention of the gyrotron and for seminal contributions to the development ofrelativistic coherent radiation sources and quasi-optical components for high-power RF systems” (Visit:

ANNIVERSARY
Institute of Applied Physics of the Russian Academy of Sciences
has marked its 40th anniversary
In May, 2017 the Institute of Applied Physics of the Russian Academy of Sciences has celebrated its 40th
anniversary. For photos and videos of this event please visit: http://www.ipfran.ru/news/40/news_40.html.

The IAP RAS is a multipurpose institution combining basic and applied research in the field of plasma
physics, high-power electronics, physics of the atmosphere, hydrophysics, and quantum electronics. The
gyrotrons, i.e., high-power millimeter-wave oscillators, and respective results on interaction of high-powerelectromagnetic radiation with plasma and matter are widely used in controlled nuclear fusion facilities. In
cooperation with the scientific and production enterprise GYCOM the IAP RAS has become one of theworld leaders in developing gyrotrons for different purposes. Theoretical and experimental achievements
in nonlinear and adaptive optics have been the basis for the construction of high-power laser systems at
the IAP RAS, including a femtosecond laser complex of petawatt power. The pioneering research in thefield of acoustics performed as early as in the 1960-1970s has led to the development of new highly
sensitive methods of nondestructive testing and defectoscopy. Many years of experience in the field of
precision optical measurements ensured the development and introduction into clinical practice of ageneration of methods and instruments of optical biomedical diagnostics. Large-scale field studies andunique solutions in low-frequency ocean acoustics resulted in the creation and industrial application ofadvanced tools of hydroacoustic metrology and diagnostics of complex vibroactive systems, theimplementation of coherent methods of high-resolution seismoacoustic diagnostics, etc. Many of theresearch lines actively developed at the IAP RAS are related to the inverse problems of remote diagnostics
and tomography of different objects. Recently studies in the topical problems in physics of condensed
media and quantum physics, attosecond physics, nanophotonics,
modeling and construction ofneuromorphic systems, the development of physical principles and technologies for the creation ofnanostructural materials, study of catastrophic phenomena in the Earth’s natural shells (ocean andatmosphere), and the development of new-generation tools and techniques for diagnostics of naturalenvironments and complex technical systems have successfully been started at the Institute. The Institutehas a powerful experimental base and a large set of modern diagnostic tools for both laboratory and field
experiments. The research activities are provided by more than 1100 employees, of which about 450 are
research scientists, including 4 full members of RAS, 7 corresponding members of RAS, 90 doctors ofscience and 197 candidates of science.

Alexander Soane wins International Vacuum Electronics Conference best student paper award”MIT graduate student Alexander Soane received the best student paper award at IEEE 18th International
Vacuum Electronics Conference (IVEC), held in London from 24 to 26 April 2017. Soane works at MIT’s
Plasma Science and Fusion Center (PSFC) on microwave sources, specifically on an amplifier for
generating high-gain, high-power, and high-frequency millimeter wave radio frequency power. Using the
PSFC’s gyrotron, he is trying to create a source for specific pulses of 140 GHz microwaves that will
excite the electron spin system in a chemical sample in a nuclear magnetic resonance spectrometer. Soanesays chemists can hope to see the signal from their spectrometer enhanced by a factor of more than 100,
allowing them to acquire data faster, cutting costs, and speeding up research into protein structure.”
