Description

ENSAR2 workshop: GEANT4 in nuclear physics

24 April 2019 - 26 April 2019 - CIEMAT Madrid, Spain

Monte Carlo simulations play a key role in the planning, realization and analysis of nuclear physics experiments and applications. For this reason, the ENSAR2 European Project is organising a workshop between the GEANT4 developers and nuclear physicist with important experience in GEANT4. The goals of the workshop are:

  • to transmit to the GEANT4 developers the priorities and needs of the nuclear physics community in terms of simulations.
  • To learn from the GEANT4 developers about the current performance of the simulation toolkit, its limitations and ideas about its future developments.
  • To facilitate the porting of code developed by nuclear physicists (inside/outside the ENSAR2 community) into the GEANT4 toolkit.
  • To promote the exchange of ideas and information between the different GEANT4 code developers and advanced users from the nuclear physics community and the GEANT4 collaboration.

The following areas of research in nuclear physics will be covered:

  • Nuclear structure: decay and in-beam studies;
  • Nuclear reactions at low and intermediate energies;
  • Underground experiments;
  • Detector development;
  • Energy applications;
  • Medical applications.

The workshop is targeted to advanced GEANT4 users and code developers in the field of nuclear physics and the GEANT4 development team.

This workshop is funded by the European Union’s Horizon 2020 research and innovation programme grant agreement No 654002.

      Nuclear reactions at low and intermediate energies: Nuclear reaction models in GEANT4

      This session is dedicated to GEANT4 developments for nuclear reactions at low and intermediate energies.

        Transport of low energy neutrons and charged particles in Geant4 35m

        Geant4 allows to use the information available in ENDF-6 format data libraries for the transport of low energy neutrons and charged particles (up to 20 MeV). This is done by the so called G4ParticleHP model (previously G4NeutronHP). We will show the performance of the model, showing its capabilities and limitations. We will also talk about how to use it and about which simulations can be done with this model and which ones can not. Finally, we will propose future developments to improve the performance of the code.

        Geant4 pre-compound model and nuclear de-excitation module 35m

        High and intermediate energy hadronic models should have a sub-model for simulation of nuclear de-excitation processes. In Geant4 there is a general pre-compound model and a general de-excitation module, which are used by many hadronic models. These models were recently modified and improved. Different aspects of these models are discussed and new validation results are presented.

        The interface of BLOB with GEANT4 35m

        Despite of its large use, the models implemented in Geant4 have shown severe limitations in reproducing the measured secondary yields in ions interaction below 100 MeV/n, in term of production rates, angular and energy distributions.
        For this reason, we coupled BLOB (Boltzmann-Langevin One Body), a models dedicated to simulate such interactions, with Geant4 and its de-excitation phase.
        BLOB is a semi-classical one-body approaches to solve the Boltzmann-Langevin equation. It includes a treatment of the mean-field propagation, on the basis of an effective interaction. BLOB introduces fluctuations in full phase space through a collision term where nucleon-nucleon correlations are explicitly involved. BLOB has been developed to simulate heavy ion interactions in the Fermi-energy regime.
        We will present the preliminary results obtained in calculating double-differential cross sections and angular distributions of the secondary fragments produced in the 12C fragmentation at 62 MeV/n on thin carbon target obtained with this model coupled with Geant4 and its de-excitation phase.

        Cross-sections of Light Nuclei in the Glauber-Gribov representation 30m

        The Glauber-Gribov approach (corrections for both elastic and inelastic nucleon screening) is considered for the description of light nucleus-nucleus cross-sections. It was found that electromagnetic nucleus radii are result in better description of measurements. The calculations are compared with experimental data for the reaction cross-sections

        Fission Models in Geant4: Status and Plans 20m

        Fission in Geant4 is currently simulated as both a separate process and as a de-excitation model in other inelastic processes. Several different models exist, each with different interfaces and functionalities. This has led to confusion about which models are used and what they do, and to the possibility of users double counting fission by incorrect assignment in physics lists. The inventory of Geant4 fission models will be discussed, highlighting the areas where physics is lacking or not yet addressed, and improvements which need to be made. Potential projects for the future will be presented, including re-organization and redesign of the fission interfaces, expansion of fission databases, physics improvement, validation and documentation.
