	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 new accelerator complex Nuclotron-based Ion Collider fAcility (NICA) is now under development and construction at JINR. Existing Alvarez-type DTL linac LU-20 is now operates as injector of light ions, polarized protons and deuterons to Nuclotron for LHEP experimental program. It provides proton beam of 20 MeV energy and light ions of 5 MeV/u energy. In 2015 the cascade transformer 800 kV which is pre-accelerator of LU-20 had been replaced by the new RFQ linac (energy 155 keV for ions with Z/A<0.5). The proposal on Alvarez linac LU-20 upgrade by a superconducting light ion linac with energy up to 50 MeV is discussed in this report.

TUPOW021	Beam Dynamics Optimization and Future Plans for LUE-200 Linac Upgrade	1788
	S.M. Polozov, T.V. Bondarenko MEPhI, Moscow, Russia A.V. Butenko, V. Kobets, A.P. Sumbaev JINR, Dubna, Moscow Region, Russia
	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.

WEZA02	The NICA Project at JINR	2061

	The physics program and the present status of the project of NICA collider, which is under construction at JINR (Dubna), are presented. The main goal of the project is to provide ion beams for experimental studies of hot and dense strongly interacting baryonic matter and spin physics. The proposed physics program concentrates on the search for possible manifestations of the phase transitions and critical phenomena in the energy region, where the excited matter is produced with maximal achievable net baryon density, and clarification of the origin of nucleon spin. The collider will provide heavy ion collisions in the energy range of √sNN=4/11 GeV at average luminosity of L=1·10²⁷cm^−2·s^−1 for 197Au⁷⁹⁺ nuclei and polarized proton collisions in energy range of √sNN=12/27 GeV at luminosity of L≥10³²cm^−2·s^-1. The key issue of the accelerator complex is application of sophisticated beam accumulation schemes and both stochastic and electron cooling methods. Strong space-charge effects in the collider arise a challenge to its optics and application of novel methods of beam stability maintenance.
