Numerical simulation of stress wave propagation in joint rock specimens with cavity defects

Frontiers in Earth Science, 2022
The process of crack initiation, propagation, and coalescence is the essential cause of rock failure. A three-dimensional numerical model based on microscopic damage mechanics is adopted to simulate the failure process and acoustic emissions (AEs) of a ...

Advances in nuclear data development for moderator and reflector design at the European Spallation Source [PDF]

EPJ Web of Conferences
Thermal neutron scattering data for neutronic design of neutron sources traditionally has been limited to a few selected materials due to the relevance of those materials to nuclear energy applications and the limitations of legacy software.

Fast neutron sensitivity for 3He detectors and comparison with Boron-10 based neutron detectors

EPJ Techniques and Instrumentation, 2019
The 3He-based neutron detectors are no longer the default solution for neutron scattering applications. Both the inability of fulfilling the requirements in performance, needed for the new instruments, and the shortage of 3He, drove a series of research ...

Protein crystallography with spallation neutrons [PDF]

Acta Crystallographica Section A Foundations of Crystallography, 2003
Spallation neutrons are ideal for diffraction studies of proteins and oriented molecular complexes. With spallation neutrons and their time-dependent wavelength structure, one can select data with an optimal wavelength band and cover the whole Laue spectrum as time (wavelength) resolved diffraction data.
