“…This is the case for the studies of alpha particle induced reactions in low-background dark matter experiments [2], fission products from nuclear reactors [3] and 𝛽-delayed neutron emitters [4]. The latter has important implications in operation of power nuclear reactors as well as in nucleosynthesis in nuclear astrophysics [5].…”

We propose an alternative approach for the detection of fast neutrons in the energy range from 10-4 to 5 MeV based on 10B-RPCs (hybrid double-gap Resistive Plate Chambers with 10B4C neutron converters) surrounded by a polyethylene moderator. The detection efficiency as a function of the neutron energy is obtained in Monte Carlo simulations performed with the Geant4 toolkit for several detector configurations. The thickness of the neutron converter is optimized for the maximum efficiency. The results show that for this type of detector it is possible to obtain an average detection efficiency larger than 50% with a weak dependence on the neutron energy. The dark count rate and gamma sensitivity are also discussed.

“…•r-process Until recently, the most favored cite of the r-process was the high entropy wind (HEW) in core collapse supernova (CCSN). The basic scenario (see, [28,29]) is that the streaming out neutrinos from the forming neutron star represent a neutrino-driven wind starting near the surface of the newly forming neutron star with a flow of neutrons and protons. In a temperature range T=(6-10)×10 9 K, the neutrons and protons combine to form alpha-particles, but with an excess of neutrons.…”

While the primordial (or Big Bang) nucleosynthesis delivers important clues about the conditions in the high red-shift universe (termed far-field cosmology), the nucleosynthesis of the heavy elements beyond iron by the r-process or the s-process deliver information about the early phase and history of the Galaxy (termed near-field cosmology). In particular, the r-process nucleosynthesis is unique, because it is a primary process that helps to associate individual stars with the composition of the protocloud. The present contribution is intended to give a brief overview about these nucleosynthesis processes and describe their link to the early universe, stellar evolution and to the chemical evolution of the Galaxy. The focus of this present contribution is on illumination the role of nucleosynthesis in the Universe.
