  The new accelerator complex Nuclotron-based Ion Collider fAcility (NICA) is now under development and construction at JINR. New complex is assumed to operate using two injectors: the Alvarez-type linac LU-20 as injector of light ions, polarized protons and deuterons and a new linac HILac of heavy ions. Now the modernization of LU-20 is also realized and old pulse DC injector is planning to replace by RFQ linac. New RFQ linac was developed and manufactured and is now under commissioning at Nuclotron injectors hall. New results of RFQ linac resonator testing and measurements, RF power load and linac testing with deuterium and carbon beam will discuss in this report.

  During a few decades axisymmetric RF structures with a focusing by means of nonsynchronous spatial harmonics of electromagnetic field are offered instead of proven RFQ. An effectiveness of these structures in the energy range up to 2 MeV was shown in a number of papers. An effectiveness of these structures in the energy range up to 7 MeV is considered in this paper. Results of an analytical investigation and a numerical simulation of self-consistent proton dynamics are presented and discussed.
