Publications, 20 July 2023

We offer to your attention a preprint “TESLA-Type Superconducting Accelerator Niobium Resonators for Electrons and Positrons” P9-2023-9 issued by the JINR Publishing Department. The authors are Mikhail Baturitsky(Stepanov Institute of Physics of National Academy of Sciences of Belarus), Yulian Budagov (JINR), Sergey Demyanov (Scientific-Practical Materials Research Centre of NAS of Belarus), Viktor Karpovich (Institute for Nuclear Problems of Belarusian State University), Alexander Kuraev (Belarusian State Univercity of Informatics and Radioelectronics), Igor Pobol (Physical-Technical Institute of NAS of Belarus), Artur Pokrovsky (PTI of NAS of Belarus), Valentina Rodionova (INP BSU), Grigory Trubnikov (JINR), Grigory Shirkov (JINR).

The monograph is devoted to the development and creation of prototypes of superconducting niobium resonators in which electromagnetic field energy is transferred to accelerated charged particles. These studies were carried out as part of JINR’s participation in the ILC project in accordance with the scientific theme 02-0-1067-2007/2015 (Leader Grigory Shirkov) “Research in the field of e+e− linear accelerators and colliders of a new generation for fundamental and applied purposes”. For this purpose, Yulian Budagov organized the production of a working sample of a TESLA-type superconducting resonator from Fermilab (USA), which was used as a reference and for setting up measuring equipment. On the initiative of Yulian Budagov, work was organized in Minsk to create superconducting microwave resonators of this type by the leading research organizations of the Republic of Belarus. A complete production cycle of manufacturing parts of superconducting niobium resonators was developed, all the necessary technological equipment was created, and two resonators were manufactured. According to the test results, a Q factor of 1.5 · 109 was achieved on one of them.

The study has been carried out at the Dzhelepov Laboratory of Nuclear Problems JINR and sent to the journal “Physics of Elementary Particles and Atomic Nuclei”.
