AB  - New beamlines for applied researches on the Nuclotron are under development within the framework of implementation of the NICA accelerator facility. Ion beams with energies of 150-800 MeV/n extracted from the Nuclotron will be used for radiobiological researches and modeling of cosmic rays interactions with microchips. Equipment of two experimental stations is under development by the JINR-ITEP-MEPhi collaboration for these applied researches. Ion beams with the energy of 3.2 MeV/n extracted from the heavy ion linac HILAc will also be used for irradiation and testing of microchips. The specialized channel will be reconstructed for investigations in the field of relativistic nuclear power at light ion energies of 0.3-4.5 GeV/n. Three new experimental areas are organized for applied physics researches within the framework of implementation of the NICA accelerator facility.

AB  - Status of the project of NICA accelerator complex, which is under construction at JINR (Dubna, Russia), is presented. The main goal of the project is to provide ion beams for experimental studies of hot and dense baryon-ic matter and spin physics. The NICA collider will pro-vide 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 lumi-nosity of L ≥ 1031cm−2·s^{−1}. NICA accelerator complex will consist of two injector chains, 578 MeV/u supercon-ducting (SC) booster synchrotron, the existing SC syn-chrotron (Nuclotron), and the new SC collider that has two storage rings each of 503 m circumference. Con-structing facility is based on Nuclotron-technology of SC magnets with iron yoke. Hollow SC cable cooled by two-phase He-flux used for operation with 10 kA currents and 1Hz cycling rate. Both stochastic and electron cooling methods are used for the beam accumulation and its stability maintenance.

AB  - A specific feature of the NICA acceleration complex is high luminosity of colliding beams. Three types of RF stations will be used in the NICA Collider to reach the necessary beam parameters. The first one is for accumulation of particles in the longitudinal phase space with the moving burrier buckets under action of stochastic and/or electron cooling systems. The second and third RF stations are for formation of the final bunch size in the colliding regime. This report presents numerical simulations of longitudinal beam dynamics which taken into account the longitudinal space charge effect during the accumulation and bunching procedures. Influence of space effects leads to some decrease in the accumulation efficiency and requires special manipulation with the 2nd and 3rd RF stations during the adiabatic capture and bunching procedures.

AB  - To implement the polarization program at the NICA complex (Dubna, Russia) the novel mode of ion polarization control - the transparent spin mode - is planned to use. To set up the transparent spin mode in the NICA collider two solenoidal snakes will be placed in straights of the Multi Purpose Detector (MPD) and the Spin Physics Detector (SPD). The beam polarization at SPD will be controlled by means of ‘‘weak’’ solenoids. The main characteristic of the transparent spin mode is the spin resonance strength, which consists of two parts: a coherent part arising due to additional transverse and longitudinal fields on the beam trajectory deviating from the design orbit and an incoherent part associated with the particles’ betatron and synchrotron oscillations (beam emittances). The resonance strength allows one to formulate requirements on the magnitudes of the control solenoids’ fields. The theoretical analysis, calculation and spin tracking simulation of the spin resonance strength in the whole momentum range of the NICA collider are presented.

AB  - SC200 is a superconducting isochronous cyclotron which generates 200 MeV, 400 nA proton beam for particle therapy. The cold-cathode-type Penning ion gauge (PIG) ion source for the internal ion source of SC200 has been selected as an alternative and preliminary designed. In this paper, design of ion source and test bench are demonstrated. Currently, the properties of ion source have been simulated for a variety of electric field distributions and magnetic field strengths. The secondary electron emission in electromagnetic field has been simulated. It provides reference for the optimization design of arc chamber. In addition, the sample of cold-cathode-type ion source has been tested on the test bench and extracted beam intensity has been measured over 200 μA.

AB  - The use of a bent crystal was investigated in order to reduce the losses at the CERN Super Proton Synchrotron (SPS) electrostatic septa (ZS) during the slow extraction of 400 GeV protons toward the North Area. The crystal, installed a few meters upstream the ZS, bends protons that would otherwise impinge on the ZS wires. Since particle deflection with good efficiency is achieved only when the crystal lattice is aligned within ~10 urad to the trajectory of the particles (at p = 400 GeV/c), a compact goniometer was built to allow the correct angular alignment of the crystal with respect to the incoming beam with a precision of few urad. In this paper, we report on the crystal features measured during a dedicated beam test by the UA9 experimental installation in the CERN H8 beam line. Details of the goniometer and its installation are also reported. The first results achieved during dedicated Machine Development (MD) sessions are finally presented.

AB  - The SC200 superconducting accelerator which is designed for proton therapy is currently under con-struction. The RF (Radio Frequency) system has been designed and constructed as a subsystem of the SC200. To verify the stability of the RF system, a high-power feeding test was performed for the cavity. This paper mainly reports on the overview of RF systems and the prelimary high-power commissioning, as well as the problems found and improvements made during the commissioning process. The results show that the RF system has initially achieved the designed goal, and each loop (amplitude, tuning, phase) can work effec-tively. The cavity can operate in a ~50 kW continuous wave state. Next, the formal RF conditioning will be carried out after the complete assembly of cyclotron, so as to confirm the cavity can run smoothly under 80 kW, which is part of the whole commissioning process.

AB  - The Nuclotron is the basic facility of JINR used to generate beams of protons, polarized deuterons and protons, and multi charged ions in the energy range of up to 5.6 GeV/n. Polarized deuteron and proton beams were obtained at the intensity of 2×10⁹ ppp and 108 ppp, respectively. The injection with RF adiabatic capture was used in two last Nuclotron runs where C⁶⁺, Xe⁴²⁺, Kr²⁶⁺ and Ar¹⁶⁺ ion beams were accelerated. The resonant stochastic extraction (RF knockout technique) was realized. The complex is now used for fixed target experiments with extracted beams and experiments with an internal target. In the near future, the Nuclotron will be the main synchrotron of the NICA collider facility being constructed at JINR. The installation in the Nuclotron of beam injection system from the Booster and of the fast extraction system in the Collider are required for its operation in the NICA complex. In the frame of the Nuclotron injection chain upgrade, a new light ion linac (LILac) for protons and ions will be built.

AB  - For heavy-ion accelerator facilities charge stripping is a key Technology: the stripping charge state, its efficiency to produce ions in the required charge state, and the beam quality after stripping substantially determine the entire accelerator performance. Modern heavy ion accelerator facilities such as the future Facility for Antiproton and Ion Research (FAIR) at GSI provide for high intensity heavy ion beams beyond 200 MeV/u. Heavy ion stripping at a lower energy enables more efficient acceleration up to the final beam energy, compared to acceleration of ions with a low charge state. Due to the high power deposited by the heavy ions in the stripping media and radiation damages if a solid target is used, self-recovering stripper media must be applied. General implementation options for different stripper target media are discussed in this paper, as well as general considerations to optimize the Linac layout through the appropriate choice of stripping medium and stripping energy. The driver Linac for the Dubna Electron-Radioactive Isotope Collider fAcility (DERICA) project, recently initiated by JINR, is foreseen to provide for 100 MeV/u Uranium beam in continuous wave mode. First layout scenarios of a one-step and a two-step DERICA-stripper approach will be also presented.

AB  - Radiation detectors based on microchannel plates (MCP) are used for measurements of the SASE process of the European XFEL. Detectors operate in a wide dynamic range from the level of spontaneous emission to the saturation level (between a few nJ and 25 mJ) and in a wide wavelength range from 0.05 nm to 0.4 nm for SASE1 and SASE2 and from 0.4 nm to 4.43 nm for SASE3. Photon pulse energies are measured by the MCPs with an anode and by a photodiode. The MCP imager measures the photon beam image with a phosphor screen. Three MCP detectors are installed, one behind each SASE undulator (SASE1, SASE2, and SASE3). Calibration and first experiments with the MCP detectors are under discussion.

AB  - The option being considered for the FCC-hh high energy injector is a superconducting synchrotron replacing the CERN SPS. The new machine would operate in a cycled mode also to feed experimental areas, much like the SPS nowadays. Due to this specific cycled operation, innovative design and development approaches is required to cope with the AC losses in the superconducting cables and iron yoke. The research joins experience accumulated at CERN and JINR respectively in the design and operation of large systems operated at 1.9 K and, in fast ramped and cycled magnets. The specified parameters are the following: magnet aperture -80 mm; aperture field - 6 T; field ramp 0.2-0.5 T/s; coil conductor - NbTi; magnetic field homogeneity between 0.12 and 6 T of the order of 5·10⁻⁴. The minimization of the cycling losses is particular important. Total thermal losses should be limited to tentatively < 2 W/m at 4.2 K. The magnet design, and the results of preliminary tests on a candidate NbTi-wire for building a model magnet are presented and discussed.
