We offer to your attention a new preprint “The Cooperation of JINR with the Scientific Organizations of the Republic of Belarus in the Area of the Superconducting Accelerator Resonators” P9-2020-22 published by the JINR Publishing Department. The authors are Budagov Yu. A. et al.

The Collaboration of Scientists and Specialists of the Republic of Belarus from the INP and NC HEP (later merged with INP BSU) оf the BSU, BSUIR, PhTI and SSPA NASB together with physicists of JINR developed, manufactured and tested at liquid helium temperature of 4.2 K three prototypes of an elliptical superconducting niobium cavity at 1.3 GHz frequency for electron and positron accelerators. The work was initiated by the International Linear Collider (ILC) project. For the first time in Belarus, the superconducting mode of operation of the cavity has been achieved, and the maximum value of the loaded Q-factor of the resonator, equal to 2,8101 · 10⁹, has been obtained with absolute matching of the cavity with the RF-path at SWR = 1.0000.

The investigation has been performed at the Dzhelepov Laboratory of Nuclear Problems.
