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

      Farooqui, Azharuddin; Jaroszuk, Wladyslaw; Ferrero, Domenico; Santarelli, Massimo; Llorca Piqué, Jordi
      Conference report
      Open Access
      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)
      Conference lecture
      Open Access
      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)
      Conference lecture
      Open Access
      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)
      Conference lecture
      Open Access
      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)
      Conference lecture
      Open Access
      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 

      Guerrro Sánchez, Carlos; Lerendegui-Marco, J.; Domingo-Pardo, C; Calviño Tavares, Francisco; Casanovas Hoste, Adrià; Cortés Rossell, Guillem Pere; Tarifeño Saldivia, Ariel Esteban (EDP Sciences, 2016)
      Conference lecture
      Open Access
      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 

      Pérez Contreras, Eloi; Serra, Maria; Ocampo-Martínez, Carlos; Llorca Piqué, Jordi (Institute of Electrical and Electronics Engineers (IEEE), 2016)
      Conference report
      Open Access
      This paper presents a new Nonlinear Model Predictive Control (NMPC) design for an Ethanol Steam Reformer with Pd-Ag membrane separation stage. The reformer is used to produce pure hydrogen able to feed a Proton Exchange ...
