“…The samples had a form of pills made of compressed yttrium powder with a diameter of 10 mm, a thickness of 1.5 mm, and a weight of ∼0.6-0.8 g [9]. The purity of used 89 Y was 99.99%.…”

“…Schema of the experimental setup and locations of yttrium activation detectors in the Quinta assembly are depicted in figure 1. Twelve yttrium samples in total were used in each irradiation of the Quinta setup in 2, 4 and 6 GeV deuteron experiments carried out in March 2011 (without lead shielding) [7], 1 and 4 GeV deuteron experiments in December 2011 (with lead shielding) [9], and 2, 4 and 8 GeV deuteron experiments in December 2012 (again with lead shielding) [8] MeV respectively were detected using gamma spectroscopy and their yields per gram of activation material per beam deuteron were determined. The acquired gamma spectra were analysed using the Deimos32 spectroscopy software [10] with all necessary spectroscopic corrections applied [11].…”

“…We simulated the isotope production in threshold (n,xn) reactions in yttrium samples and compared them with the experimental results obtained by the group from the National Centre for Nuclear Research in Otwock-Świerk, Poland [7][8][9]. The Monte Carlo simulations of the yields of activation reactions in the samples were performed with the MCNPX code version 2.7.0 [16].…”

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.
