    • System efficiency analysis of dual interconnected bubbling fluidized bed reactors for solar fuel production 

      Uddin, Azhar; Jaroszuk, Wladyslaw; Ferrero, Domenico; Santarelli, Massimo; Llorca Piqué, Jordi (Universidade do Minho, 2019-08-19)
      Text en actes de congrés
      Accés obert
      Chemical looping syngas production is a two-step syngas fuel production process that produces CO and H 2 . The process is composed of two fluidized bed reactors (oxidation reaction and reduction reactor), oxygen carriers ...

    • Monte Carlo simulations of the n TOF lead spallation target with the Geant4 toolkit: A benchmark study 

      Lerendegui-Marco, J.; Cortés-Giraldo, M.A.; Guerrero Sánchez, Carlos; Calviño Tavares, Francisco; Casanovas Hoste, Adrià; Cortés Rossell, Guillem Pere (EDP Sciences, 2016)
      Comunicació de congrés
      Accés obert
      Monte Carlo (MC) simulations are an essential tool to determine fundamental features of a neutron beam, such as the neutron flux or the ¿ -ray background, that sometimes can not be measured or at least not in every position ...

    • Characterization of the n TOF EAR-2 neutron beam 

      Chen, Y.L.; Tassan Got, Laurence; Audouin, Ludmila; Calviño Tavares, Francisco; Casanovas Hoste, Adrià; Cortés Rossell, Guillem Pere (EDP Sciences, 2016)
      Comunicació de congrés
      Accés obert
      The experimental area 2 (EAR-2) at CERNs neutron time-of-flight facility (n TOF), which is operational since 2014, is designed and built as a short-distance complement to the experimental area 1 (EAR-1). The Parallel Plate ...

    • The n TOF facility: Neutron beams for challenging future measurements at CERN 

      Chiaveri, E.; Aberle, O.; Andrzejewski, Józef; Calviño Tavares, Francisco; Casanovas Hoste, Adrià; Cortés Rossell, Guillem Pere; Tarifeño Saldivia, Ariel Esteban (EDP Sciences, 2016)
      Comunicació de congrés
      Accés obert
      The CERN n TOF neutron beam facility is characterized by a very high instantaneous neutron flux, excellent TOF resolution at the 185m long flight path (EAR-1), low intrinsic background and coverage of a wide range of neutron ...

    • 7Be(n,alpha) and 7Be(n,p) cross-section measurement for the cosmological lithium problem at the n TOF facility at CERN 

      Barbagallo, Massimo; Colonna, Nicola; Aberle, O.; Calviño Tavares, Francisco; Casanovas Hoste, Adrià; Cortés Rossell, Guillem Pere; Tarifeño Saldivia, Ariel Esteban (EDP Sciences, 2016)
      Comunicació de congrés
      Accés obert
      The Cosmological Lithium Problem refers to the large discrepancy between the abundance of primordial 7Li predicted by the standard theory of Big Bang Nucleosynthesis and the value inferred from the so-called “Spite plateau” ...

    • Time-of-flight and activation experiments on 147 Pm and 171 Tm for astrophysics

      Comunicació de congrés
      Accés obert
      The neutron capture cross section of several key unstable isotopes acting as branching points in the s-process are crucial for stellar nucleosynthesis studies, but they are very challenging to measure due to the difficult ...

    • Nonlinear model predictive control for hydrogen production in an ethanol steam reformer with membrane separation
