We determined the distribution of activation products inside magnet coils a medical cyclotron that has been operational for fifteen years. Besides FLUKA, we based our approach on new software tools (RAW and ActiWiz) developed high-energy accelerators at CERN. A combined analysis measurements with Monte-Carlo simulations resulted in detailed three-dimensional radiological characterisation coils....

in this research graphene oxide was synthesized by two methods. these methods were achieved by changing the improved hummers’ and modified hummers’ methods. structure of graphene oxide was characterized by scanning electron microscopy (sem) images, x-ray diffraction (xrd) patterns, raman spectroscopy and fourier transform infrared (ftir) spectra. according to sem image, the thickness of graphen...

The NEAR Station is a new experimental area developed at the n_TOF Facility CERN. activation station of underwent characterization beam following installation Spallation Target. commissioning neutron comprises set simulations made with FLUKA code and verification. determination spectrum was using techniques three separate set-ups. Two set-ups were based on Multi-foil Activation technique (MAM-1...

This paper is a continuation of the preliminary dosimetric evaluation of source terms at PW laser systems [1] the proton case. The main acceleration mechanisms and the associated characteristics of the accelerated proton beams were briefly presented. FLUKA and GEANT4 Monte Carlo transport codes were used to compute absorbed doses due to three proton beams of well defined energy and spatial dist...

The HARP experiment at the CERN Proton Synchroton has collected data for hadroproduction measurements with a large set of targets, ranging from hydrogen to lead, in the momentum range 3.0-15 GeV/c, covering an extended angular range (0.025 ≤ θ ≤ 2.15 rad) with a redundant particle identification. Obtained results may be used for the tuning of neutrino beamline simulations, going from convention...

The in-beam PET technique for quality assurance of C therapy is based on the comparison of β-activity distributions measured during therapeutic irradiations with those predicted from the treatment plan. The generalisation of this method to all species of therapeutically relevant ions requires a precise description of both the stopping process and the nuclear interactions of the projectiles in t...
