  A superconducting or partially superconducting linac is discussed as new injector for Nuclotron-NICA complex. New linac will accelerate protons up to 25 MeV (and up to 50 MeV at the second stage of the project) and light ions to ~7.5 MeV/u. The progress in R&D of QWR and HWR superconducting cavities is discussed in this report. The design of QWR and its normal conducting copper model is finished and PTI NANB is ready to manufacture of the prototype. Two designs of HWR were discussed: one with a cylindrical central conductor and another with the conical one. The electrodynamics design of HWR had been finished before now but it should be corrected taking into account some manufacture problems. Current results of the development of the RF coupler and the test cryostat will also present .
