Experimental 325 MHz Section with Superconducting Cavities of Linac for the Injection Facility of the NICA Project
摘要
Scientific institutes from Russia and the Republic of Belarus have been collaborating on superconducting accelerating cavities for the new LILac (Light Ion Linac) modular linac injector since 2015 [1–3]. The injector is intended for the ion collider within the framework of the Nuclotron NICA project. (Joint Institute for Nuclear Research (JINR), Dubna, Russian Federation). The development of high-frequency superconductivity technologies is a key task of Russian–Belarusian cooperation. Three cavities (one prototype and two test samples) have been fabricated and tested in cold conditions in 2023 [4], [5]. Two cavities and a cryomodule for four cavities are being developed jointly with the Institute of Modern Physics (IMP, Lanzhou, China). This article reports on the creation of an experimental bench, testing cavities, and the results of modeling the dynamics of particles for several beam transport channel layouts when arranging a cryomodule as part of an injection complex accelerator.
