TUCHY01	Muon Collider Design Status	emittance, collider, proton, acceleration	20
	Y. Alexahin Fermilab, Batavia
	Muon Collider (MC) - proposed by G. I. Budker and A. N. Skrinsky almost half a century ago - is now considered as the most exciting option for the energy frontier machine in the post-LHC era. A national Muon Accelerator Program (MAP) is being formed in the USA with the ultimate goal of building a MC at the Fermilab site with c.o.m. energy in the range 1.5-3 TeV and luminosity of ~1-5*10³⁴ cm^-2s-1. As the first step on the way to MC it envisages construction of a Neutrino Factory (NF) for high-precision neutrino experiments. The baseline scheme of the NF-MC complex is presented and possible options for its main components are discussed.

	New crystal technique – bent crystal array and veer – type reflector based on straight crystals were used like first stage in collimation system at U-70 accelerator. Efficiency of collimation was enhanced up to 90% in two-stage collimation system which included first crystal stage and long steel absorber like second stage. While in previous one-stage system without crystal only 40% protons hit deeply in absorber. For data taking and analysis of information modified modern beam diagnostic system was applied.

TUPSA018	Intercation of the Biomolecular Ions with the Electron Target in the Electrostatic Storage Ring	ion, electron, storage-ring, resonance	80
	S. G. Shirkov JINR, Dubna, Moscow Region
	A nanostructure of the radiation damages is formed at an interaction of decelerated protons or carbon ions with DNA molecules at hadron therapy. A local interaction of the ion beam with the bimolecular structures in the human cells is defined mainly by parameters of the ion tracks. The track core is connected with ionization properties of the charged ion, its cross-section sizes are defined by the delta-electrons. The delta-electron energy varies statistically from several eV to few keV therefore they lead to substance ionization along their trajectory on a distance several nanometers from that point where they were produced. Interaction of the delta-electrons with DNA molecules and other biological structures is one of the important mechanisms realized in process of the hadron therapy. A study of interaction of the accelerated biomolecular ions with an electronic target in electrostatic storage ring was performed for modeling of an input of the delta-electrons in processes of the hadron therapy.

	A schematic diagram of heavy ion injector based on laser ion sources is described. Two different basic laser configurations used in ITEP synchrotron. First laser excels in simplicity and consists of CO2 free-running laser that is applied for carbon target plasma heating and ionization at laser power density q=3·1012W/cm² to create high current C⁴⁺ ion beam. Second master oscillator-amplifier (MOPA) laser configuration intends for production super high laser intensity at a target to provide considerable charge state in a plasma of heavy elements (Al, Fe, Ag etc). This laser configuration is founded on original physical principle* that simplifies the installation and ensures high reliability for long term operation. Laser characteristics for the different laser scheme and ion current for injector outlet beam of C⁴⁺ and Ag⁺19 are shown in this paper. The latter was accelerated in synchrotron for energy up to 100 MeV/u. * K. N. Makarov et al. Quantum Electronics (Russian), 2001, 31 (1), pp. 23-29

THPSC022	Development and Application of Electron Linac Electromagnetic Devices for Radiotechnologies	linac, electron, controls, pick-up	369
	V. A. Shendrik, A. N. Dovbnya, A. E. Tolstoy NSC/KIPT, Kharkov
	The creation and subsequent service of modern electron linear accelerators at the NSC KIPT have brought evidence for possible successful introduction of radiotechnology processes using electron irradiation. A further extension and complication of physical problems solvable on the basis of radiotechnologies have put forward new and increased requirements for the systems of beam scanning, extraction and formation on the targets and extended irradiated objects. The results of applying our methods developed for prompt measurement of the kinetic energy of the scanned electron beam are presented. For measurement and continuous control of the electron energy the hodoscope magnetic spectrometer technique has been used. The spectrometer includes only one deflecting magnet and has no magnetic focusing. If the real field topography in the magnet is known in detail, then using the input and output coordinates of deflected particles it is possible to determine their energy, and also the chromaticity of electron beam. The step-pulse scanning of the beam is realized through the use of an air-core short-pulse electromagnet. Development and tests of separate units of the device are under way

The equipment of the accelerator is mostly located inside the irradiator including the HV power supply system, magnetron modulator and control system blocks. Using this yoke, the irradiator is installed on a bridge crane, which ensures its high manoerability necessary to test products of complicated geometry. Size of the irradiator without yoke is 2040950950 mm. In 2010, the accelerator was put into operation at the "Izhorskie Zavody", St. Petersburg. The UEL-10-D accelerator can be also used in radioscopic or tomographic systems.

	V. Zakutin, A. N. Aksyonova, A. N. Dovbnya, S. D. Lavrinenko, V. N. Pelykh, N. N. Pilipenko, N. G. Reshetnyak NSC/KIPT, Kharkov
	The paper presents the results of investigations on the zirconium specimen surface after irradiation them with an electron beam from the accelerator. The operating conditions were the following: electron energy from 7 to 80 keV, pulse duration of 15 μs, pulse frequency of 2 Hz. for two modes of the energy density on the samples, namely, 10 J/сm2 and 20 J/сm2. The experiments have demonstrated that the irradiation leads to the noticeable smoothing of the specimen surface roughness, the surface becomes smoother and unruffled. The results of investigations on the microhardness of irradiated and unirradiated areas of the zirconium specimen surface areas show that the microhardness value has been increased by ~20% of the initial value (1920 MPa) for the irradiation energy density of 10 J/cm² and by ~35% for 20 J/cm², that can be related with a different quantity of an transferred energy of the irradiated surface. By choosing the optimum electron irradiation characteristics this technique may be recommended for hardening and modification of the near-surface layer of zirconium materials applied in the nuclear-power engineering.
