  1. 149. The GECO project
    Enrico Bagli (FE)
    29/09/2016, 11:20
    A fundamental aspect of a successful physics experiment is the availability of a reliable and precise simulation code. In particular, Geant4 has seen a large expansion of its user community in recent years. Currently, the toolkit does not allow the simulation of particles interacting with other than amorphous states of matter. The GECO project is devoted to the development a general framework...

  2. 164. Ab-initio Monte Carlo simulations of relativistic particle scattering and radiation in oriented crystals
    Alexei Sytov (FE)
    29/09/2016, 11:50
    Relativistic particle interaction with oriented crystals combines both classical and quantum features. Coherent particle scattering is described by the average (Lindhard) potential of planes and strings while quantum treatment is necessary to describe the incoherent scattering by both electrons and atomic cores. The latter has to be separated into large-angle single and small-angle multiple...

  3. 27. Channeling of protons in radially compressed chiral carbon nanotubes
    Dr Stylianos Sarros (Researcher)
    29/09/2016, 12:05
    Channeling of 10 MeV protons in radially compressed chiral carbon nanotubes is considered. Monte Carlo simulation program is used for the calculation of the trajectories, energy losses and angular distributions of protons in nanotubes of various lengths and compression, where the potential in Doyle-Turner approximation is used to describe the interaction between a proton and a nanotube. Carbon...

  4. 185. The X-ray characteristic line in the framework of the Boltzmann transport equation
    Prof. Jorge Eduardo Fernandez (Alma Mater Studiorum University of Bologna)
    29/09/2016, 12:20
    The emission of characteristic lines after x-ray excitation is usually explained as the consequence of two independent and consecutive physical processes: the photoelectric ionization produced by the incoming photons and the successive spontaneous atomic relaxation. However, this is not the only mechanism for the formation of the characteristic lines. In first place, the photoelectric effect...

  5. 172. Quantitative measurements of fuel spatial densities from GDI sprays through optical and x-ray based techniques
    Luca Marchitto (Istituto Motori- IM)
    29/09/2016, 12:35
    This paper reports the results of an experimental investigation to characterize the inner structure of a high-pressure gasoline spray injected by a 6-hole nozzle for Direct Injection Spark Ignition (DISI) engines. A desktop facility based on polycapillary optics system, providing a high flux beam with low divergence has been used. Both x-ray µ-tomography and radiography techniques have been...

  6. 116. A collimation system for ELI-NP Gamma Beam System – design and simulation of performance
    Dr Gianfranco Paternò (FE), Paolo Cardarelli (FE)
    29/09/2016, 12:50
    ELI-NP is one of the three pillars of ELI (Extreme Light Infrastructures) European Project, to be built in Bucharest, Romania. This facility will host the Gamma Beam System (GBS), an intense and monochromatic gamma beam source based on inverse Compton interaction between a high-power laser and an accelerated electron beam produced by a warm linac. The EuroGammaS association, composed by many...
