Research and design of a new RFQ injector for modernization of the LU-20 drift-tube linac.

A new NICA heavy-ion collider is now under construction at JINR. At the same time, the Nuclotron facility is being modernized. A joint team from the JINR, MEPhI, and ITEP are now reconstructing a proton and light-ion injection system. New results of the RFQ linac resonator testing and measurements and RF power load are discussed in this article. [ABSTRACT FROM AUTHOR]
