The new JINR project [1] is aimed at studies of highly excited nuclear matter created in nuclei by a high-energy deuteron beam. studied through observation its particular decay products - pairs energetic particles with wide opening angle, close to 180°. precision hybrid magnetic spectrometer SCAN-3 be built for detecting charged (π±, K±, p) and neutral (n) produced the Nuclotron internal target dA collisions. One main complex tasks study low-energy ηA interaction search η-bound states...
A comparative study of the energy efficiency proton beams with an from 0.5 GeV to 4 and light ion ( 7 Li, 9 Be, 11 B, 12 C) energies 0.25 AGeV 1 in natural enriched quasi-infinite U target is presented. The numerical results on particle transport interaction are obtained using code Geant4. following optimization issues addressed: beam window dimensions, possibility use a core low Z materials. best solution for ADS point view gain miniaturization Li or Be 0.3–0.4 core.
Proton and ion beams with the initial energy between 0.2 AGeV 10 were analyzed respect to neutron production in different targets, number spatial distribution of fission acts deposited uranium targets.In this range two models for hadronic inelastic interaction are suitable: bertini cascade binary cascade.In thin medium thickness targets both produce results good agreement experimental data.In very thick use gives about times lower than data.For reason last model was chosen modeling...
Abstract A ridge carbon beam filter for Spreading Out the Bragg Peak (SOBP) up to 20 mm in targeted area has been designed and experimentally tested. The instrument was constructed of Plexiglas with a density 1.165 g/cm3 “teeth” structure period 2.5 mm. design is based on simple analytical model detailed GEANT4 Monte Carlo simulations. In-beam test measurements were performed 500-MeV/u 12C at Nuclotron facility Joint Institute Nuclear Research (JINR) Dubna. can be used as static device...
The spatial distribution of neutron fluences in the extended uranium target (“Quinta” assembly) irradiated with 0.66 GeV proton, 4 AGeV deuteron and carbon beams was studied using reactions different threshold energy (Eth). data sets were obtained 59Co samples. accumulation rates for following isotopes: 60Co (Eth 0 MeV), 59Fe 3 58Co 10 57Co 20 56Co 32 47Sc 55 48V 70 MeV) measured HPGe spectrometer. experimental compared predictions simulations Geant4 code. Substantial difference between...
The new concept of light nuclear beams instead proton for ADS is substantiated. influence the target structure on energy efficiency 0.5-4 GeV and 0.25 – 0.5 AGeV ion studied. consists rods with different composition (metal, oxide, carbide) levels enrichment in order to implement a criticality coefficient 0.96 -0.97, which ensures safe operation. cooling metals (lead, lead-bismuth eutectic - LBE, sodium) compared. use converters from very materials (lithium, beryllium, carbon) their neutron...
Cross sections of spallation reactions 181 Ta, 197 Au, 207 Pb, 209 Bi, 232 T h, 238 U heavy metals induced by deuterons with energy 2, 2.94, 3.5 GeV were determined.The deuteron beams extracted from the Nuclotron accelerator at Laboratory High Energy Physics, JINR, Dubna, Russia.Spallation cross measured using solid state nuclear track detectors (SSNTD) and activation gamma-spectroscopy.Due to lack data in range high energies experimental results could be added international database.
