  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.

  The IREN facility (Intense Resonance Neutron Source) is now been tested and upgraded in JINR. The linear electron accelerator LUE-200 is used to generate intense fluxes of resonant photo-neutrons. Linac should deliver up to 200 MeV electron beam with 1 A or more current in 100 - 200 ns pulses. It consists of electron source, LEBT including buncher and two main accelerating sections (only one is installed up to now). Test operations shows that beam loading sufficiently influences the output beam parameters and beam energy after first section decreases from planned 55-60 MeV to 35 MeV. The buncher doesn't provide an efficient beam bunching also and beam recapturing by main section due to this is very low. Dynamics of the electron beam for traveling wave S-band linac LUE-200 was studied by numerical simulations. In report results of beam dynamics simulation and optimization taking into account beam loading discuss, parameters for new more effective buncher presents and first results of such buncher development shows.
