30th Joint Russian-German Meeting on ECRH and Gyrotrons

This meeting was already the thirtieth meeting in the series of annual workshops organized within the framework of the scientific and engineering cooperation plan in the field of fusion research between the Rosatom State Corporation (formerly, the Nuclear Energy Agency of Russia) and Bundesministerium für Bildung und Forschung, Bundesrepublik Deutschland.
The traditional participants of the meeting are the research leaders in the field: Institute of Applied Physics of the Russian Academy of Sciences (IAP RAS), Nizhny Novgorod, Russia; Kurchatov Institute, Moscow, Russia; A.M. Prokhorov General Physics Institute (GPI) of the Russian Academy of Sciences, Moscow, Russia; Novosibirsk State University, Novosibirsk, Russia; Karlsruhe Institute of Technology (KIT Karlsruhe, formerly FZK), Karlsruhe, Germany; Institut für Grenzflächenverfahrenstechnik und Plasmatechnologie der Universität Stuttgart (IGVP), Stuttgart, Germany; Max-Planck-Institut für Plasmaphysik (IPP Garching und Greifswald), Bruker BioSpin (Rheinstetten); and the Scientific and Production Enterprise “GYCOM”, Nizhny Novgorod, Russia.
The workshop was organized by IAP RAS and GYCOM under the auspices of the Russian Foundation for Basic Research at the Rublev Hotel Club in Gorodets, Nizhny Novgorod Oblast. The workshop sessions were attended by more than 80 participants, who made and discussed 47 presentations. Crucial scientific issues were not bounded by the workshop program and were discussed during the entire duration of the workshop.
It should be noted that currently, the topics of the workshop embrace a wider range of problems compared with that reflected in the workshop title. For example, along with the tasks related directly to electron cyclotron heating, stabilization and diagnostics of plasma, and the gyrotrons used for these purposes, great attention is given to the studies aimed at development of new technologies for material processing using high-power microwaves. The workshop participants presented a variety of new results of using gyrotron setups for high-resolution spectroscopy, as well as chemical and medico-biological applications. An important part of the workshop program are such applied tasks, as development of new promising sources of microwave radiation for various applications, systems for conversion and low-loss transmission of such waves to long distances, as well as design of high-capacity microwave input/output windows. These tasks require deep theoretical and experimental studies, on the one hand, and new engineering approaches and solutions, on the other.
Having analyzed the presentations of the workshop participants, one could state that the studies aimed at gyrotron development and application correspond to the cutting-edge problems of the modern science. The level of the most works presented at the workhop correspond to the forefront of the global modern research or surpasses it. The Russian researchers (at IAP, Gycom, Kurchatov Institute, and GPI) have accumulated a great experience of designing and using megawatt gyrotrons and radiation transmission systems. In recent years, gyrotrons and transmission lines were manufactured, delivered, and operated in controlled fusion setups in many countries of the world. The IAP team is the acknowledged leader in designing physical basics of the technological processes involving millimeter waves. In the recent decade, IAP RAS created unparalleled special gyrotron complexes for comprehensive studies in the field of high-temperature microwave processing of materials. As of now, such complexes are delivered to leasing research centers in the USA, Europe, Japan, China, and Korea. Qualified scientific personnel available in Russia (IAP, GTI, PTI, Institute of Nuclear Physics, Kurchatov Institute, and GYCOM) are capable of conducting research at the highest possible level in all the above-specified fields. However, it should be acknowledged that provision of the Russian teams with scientific and technological equipment is still inferior to that in the best foreign research centers, which makes a significant portion of the related research effort in Russia focus on the facilities abroad.
