    • First results from the HENSA/ANAIS collaboration at the Canfranc Underground Laboratory 

      Mont i Geli, Nil; Tarifeño Saldivia, Ariel Esteban; Orrigo, S.; Beristáin Jiménez, José Antonio; Agramunt Ros, Jorge; Camarero Palao, Julio A.; Bemmerer, D.; Calviño Tavares, Francisco; Cortés Rossell, Guillem Pere; Dillmann, Iris; Tolosa Delgado, Alvaro (Institute of Physics (IOP), 2021-12-01)
      Article
      Accés obert
      The HENSA/ANAIS collaboration aims for the precise determination of the neutron flux that could affect ANAIS-112, an experiment looking for the dark matter annual modulation using NaI(Tl) scintillators. In this work, the ...

    • Measurement of the neutron capture cross section of 236-U 

      Calviño Tavares, Francisco; Cortés Rossell, Guillem Pere; Poch Parés, Agustí; Pretel Sánchez, Carme (2006)
      Text en actes de congrés
      Accés obert
      In this paper we describe the 236U(n,γ) reaction cross section measurement at the GELINA white pulsed neutron source of the Institute for Reference Materials and Measurements (IRMM) in Geel. The sample was placed in the ...

    • Measurement of the resonance capture cross section of 204,206-Pb and termination of the s-process 

      Calviño Tavares, Francisco; Cortés Rossell, Guillem Pere; Poch Parés, Agustí; Pretel Sánchez, Carme (American Institute of Physics (AIP), 2005)
      Text en actes de congrés
      Accés restringit per política de l'editorial
      The neutron capture cross sections of 204;206Pb have been measured with high resolution at the n_TOF facility of CERN (Geneva) [5]. The neutron capture cross section of 204Pb is of particular relevance in astrophysics, since ...

    • Measurements of the 90,91,92,94,96-Zr(n, gamma) cross-sections at n TOF 

      Calviño Tavares, Francisco; Cortés Rossell, Guillem Pere; Poch Parés, Agustí; Pretel Sánchez, Carme (Elsevier Science Publishers B.V. NORTH HOLLAND, 2004)
      Article
      Accés obert
      Neutron capture cross sections of the 90,91,92,94,96Zr have been measured over the energy range from 1 eV to 1 MeV at the spallation neutron facility n TOF at CERN in 2003. The innovative features of the neutron beam, in ...

    • Monte Carlo simulations for the study of a moderated neutron detector 

      Gómez Hornillos, María Belén; Gorlychev, V.; Caballero Folch, Roger; Cortés Rossell, Guillem Pere; Poch Parés, Agustí; Pretel Sánchez, Carme; Calviño Tavares, Francisco (2011-08-12)
      Article
      Accés obert
      This work presents the Monte Carlo simulations performed with the MCNPX and GEANT4 codes for the design of a BEta deLayEd Neutron detector, BELEN-20. This detector will be used for the study of beta delayed neutron emission ...

    • Simultaneous measurement of the neutron capture and fission yields of 233-U 

      Calviño Tavares, Francisco; Cortés Rossell, Guillem Pere; Poch Parés, Agustí; Pretel Sánchez, Carme (EDP Sciences, 2007)
      Text en actes de congrés
      Accés obert
      We have measured the neutron capture and fission cross section of 233U at the neutron time-of-flight facility n TOF at CERN in the energy range from 1 eV to 1 MeV with high accuracy by using a high performance 4π BaF2 ...

    • The CERN n_TOF facility: a unique tool for nuclear data measurement 

      Mingrone, Federica; Aberle, O.; Andrzejewski, Józef; Audouin, Ludmila; Bécares, Vicente; Bacak, M.; Barbagallo, Massimo; Barros, S.; Becvar, F.; Beinrucker, C.; Berthoumieux, Eric; Billowes, J.; Calviño Tavares, Francisco; Casanovas Hoste, Adrià; Cortés Rossell, Guillem Pere (2015)
      Text en actes de congrés
      Accés obert
      The study of the resonant structures in neutron-nucleus cross-sections, and therefore of the compoundnucleus reaction mechanism, requires spectroscopic measurements to determine with high accuracy the energy of the neutron ...
