The 27th Russian Particle Accelerator Conference (RuPAC-2021) took place at the “Dubna” Resort Hotel in Alushta from 26 September to 2 October. The Conference was organized by the Scientific Council of RAS on Charged Particle Accelerators and the Joint Institute for Nuclear Research. The year of the Conference is of special importance to JINR as it celebrates the 65th anniversary of its founding.

The aim of the Conference was to share information and discuss a range of topics of modern accelerator science and technology, as well as to present new projects of accelerators and accelerator complexes. Among the latter, new projects under construction aroused increased interest: NICA (Nuclotron-based Ion Collider fAcility, JINR), SKIF (Siberian Ring Photon Source, Boreskov Institute of Catalysis and Budker Institute of Nuclear Physics of the Siberian Branch of RAS), HIAF (High Intensity Heavy Ion Accelerator Facility, China), Kurchatov Synchrotron Radiation Source (NRC “Kurchatov Institute”, Moscow), Powerful Long-Pulse THz-Band Bragg FEL Based on Linear Induction Accelerator (IAP RAS, Nizhny Novgorod).

A large number of papers were dedicated to accelerator science and technology, new ideas and proposals for their development. Proposals for the use of accelerators in technology and medicine were presented in seven oral reports at the final session of the Conference, as well as in many poster presentations.

A special session was dedicated to the memory of outstanding accelerator physicist Evgeny Denisovich Donets who passed away this year.

A group of participants of the Conference (Prof. S. Polozov (MEPhI) and others) initiated a session to discuss problems of teaching physics and mathematics in universities, which aroused big interest. Based on the proceedings of the session, there will be developed a letter with suggestions for the Ministry of Science and Higher Education of the Russian Federation.

In total, 147 participants attended RuPAC-2021 (including 12 online speakers) from 25 institutions, both Russian (21) and foreign (4). Among the presented papers, there were nine invited ones (including three online), 49 oral reports (nine of them online) and 133 poster presentations.

On one of the Conference days D.Kamanin delivered a lecture devoted to the 65th anniversary of JINR, which the audience met with interest. In addition, a lecture “2021 — the Year of Science and Technology in Russia” by M.Itkis served as a bright culmination on the last day of the Conference.

Traditionally, the Organizing Committee of the Conference held a competition of scientific papers presented by young scientists (for authors under the age of 35 inclusive). An ad hoc jury formed out of the leading representatives of Russian accelerator laboratories and chaired by Professor V. Telnov (Budker Institute of Nuclear Physics of the Siberian Branch of RAS) selected the laureates. The jury took a decision to award four diplomas this year, one of them being a group diploma. Its owners became scientists from VBLHEP JINR, who presented a series of papers on the development of unique technology and production of superconducting magnets for the NICA accelerator complex and SIS-100 synchrotron (FAIR project, Germany): A. Bortsova, D. Zolotykh, S. Korovkin, D. Nikiforov, T. Parfilo, M. Shandov, A. Shemchuk, Yu. Bespalov, I. Donguzov, E. Zolotykh, B. Kondratyev, I. Nikolaychuk, M. Petrov, and D. Khramov.

Personal awards were won by K.Gikal for the technology of heavy-ion beam generation on the DC-280 cyclotron (FLNR JINR), I.Gorelyshev (JINR VBLHEP) for the design of a stochastic cooling system for the NICA collider, and Yu. Osina (Efremov Scientific Research Institute of Electrophysical Apparatus, St.Petersburg) for the design of a multicharged ion cyclotron. All the laureates received the 1st-degree prizes.

Traditionally, all the RuPAC papers (as well as of other conferences on accelerator physics) are published on the JACoW website (www.jacow.org).
