“…The beam integral was determined with around 10% accuracy due to the fit of the excitation function of the 27 Al(d,3p2n) 24 Na monitoring reaction as only 3 values for this reaction cross section are present in the EXFOR database in the GeV energy range [12,13]. The beam position and profile were determined using the solid state nuclear track detectors (SSNTD) by means of the measurement of distribution of induced fission rates by the beam in natural lead samples [14,15]. A fit of the experimental data by Gaussian distribution in the horizontal and vertical direction was used as input parameters for the particle source in the Monte Carlo simulations.…”

Abstract. The international collaboration Energy and Transmutation of Radioactive Waste (E&T RAW) performed intensive studies of several simple accelerator-driven system (ADS) setups consisting of lead, uranium and graphite which were irradiated by relativistic proton and deuteron beams in the past years at the Joint Institute for Nuclear Research (JINR) in Dubna, Russia. The most recent setup called Quinta, consisting of natural uranium target-blanket and lead shielding, was irradiated by deuteron beams in the energy range between 1 and 8 GeV in three accelerator runs at JINR Nuclotron in 2011 and 2012 with yttrium samples among others inserted inside the setup to measure the neutron flux in various places. Suitable activation detectors serve as one of possible tools for monitoring of proton and deuteron beams and for measurements of neutron field distribution in ADS studies. Yttrium is one of such suitable materials for monitoring of high energy neutrons. Various threshold reactions can be observed in yttrium samples. The yields of isotopes produced in the samples were determined using the activation method. Monte Carlo simulations of the reaction rates leading to production of different isotopes were performed in the MCNPX transport code and compared with the experimental results obtained from the yttrium samples.

“…In this case, the definition of thick is where the thickness of the foil is larger than the range of the fission fragments in the foil material. The SSNTD used in this work was synthetic muscovite mica, where the calibration factor for thick 232 Th, w Th has been calculated previously [27]. A weighted mean value of (8.97 AE0:22Þ Â 10 18 tracks cm À2 (fissions per atom) À1 obtained from the theoretical and Monte Carlo simulations of Hashemi-Nezhad et al was used [27].…”

An earlier study measuring the thorium fission rate in a fast spallation and neutron field found close agreement between experimental and calculated results with the use of this value [28].…”

Cross sections of spallation reactions of 181 Ta, 197 Au, 207 Pb, 209 Bi, 232 T h, 238 U heavy metals induced by deuterons with energy of 2, 2.94, 3.5 GeV were determined. The deuteron beams were extracted from the Nuclotron accelerator at the Laboratory of High Energy Physics, JINR, Dubna, Russia. Spallation reactions cross sections were measured using solid state nuclear track detectors (SSNTD) and activation gamma-spectroscopy. Due to the lack of cross sections data in the range of high energies the experimental results could be added in the international database.
