Abstract
| Researchers and specialists of the Institute of Nuclear Problems of the Belarusian State University, Belarusian State University of Informatics and Radio Electronics, Physical-Technical Institute, and the Research and Production Center for Material Science of the National Academy of Sciences of Belarus in collaboration with JINR physicists have developed, produced, and tested at the liquid helium temperature of 4.2 K, three pilot elliptical superconducting niobium cavities at a frequency of 1.3 GHz for accelerators of electrons and positrons. The cavities are constructed in the framework of the International Linear Collider (ILC) project. For the first time in Belarus, the cavities operated in superconducting mode, and the maximum value of the loaded Q-factor of the resonator equal to 2.8101 × 10$^{9}$ was obtained with the absolute matching of the cavity and the RF path at the standing wave ratio of 1.0000. |
