“…Instead, a muon veto can in principle be achieved in two different ways: By covering the outside of the large detector array with a veto detector that is many square meters large [46], or by using many closely packed germanium detectors that function as a veto detector for each other, using γ-ray tracking and pulse shape discrimination techniques [47].…”

Shallow-underground accelerator sites for nuclear astrophysics: Is the background low enough?

Abstract. In order to reliably estimate the rate of a charged particle induced nuclear reaction in a nonexplosive astrophysical scenario, its cross-section must be measured far below the Coulomb barrier. However, at the corresponding energies the cross-section values are very low, so that the experimental counting rate is dominated by cosmic-ray induced background, even if a suitable anticoincidence shield is applied. This problem can be overcome by performing an accelerator-based experiment in a deep underground site, as has been done with great success at the LUNA 0.4 MV accelerator in Gran Sasso, Italy. Several underground accelerators with higher beam energy are in the planning phase worldwide. All of them are shielded by over 1000 m of rock, a depth at which cosmic-ray effects are negligible for the purposes of nuclear astrophysics experiments. It is shown here that a combined approach, using a shallow-underground laboratory below 47 m of rock and an active shield to veto surviving muons in simple detectors, results in a background level that is not far from that of deep underground sites. Data have been obtained using two "traveling" γ-detectors. They have been transported both shallow underground, to the Dresden Felsenkeller in Germany, and deep underground, to the Gran Sasso laboratory in Italy. As shallow-underground facilities are more easily accessible than deep-underground ones, the present finding holds the promise of greatly accelerated progress in the field of cross-section measurements for nuclear astrophysics.

Nucleon-nucleon correlations probed at far sub-Coulomb energies

et al. 2017

Abstract. Excitation functions of one-and two-neutron transfer channels have been measured for the closed shell 40 Ca+ 96 Zr and superfluid 60 Ni+ 116 Sn systems from the Coulomb barrier energy to energies far below. By using the unique PRISMA performance in terms of resolution and efficiency, measurements at very low bombarding energies have been performed. In the case of the 60 Ni+ 116 Sn system, a complementary particle-γ coincident measurements provide the ground and excited state populations. The experimental transfer probabilities have been compared with semiclasical microscopic calculations that incorporate nucleon-nucleon correlations, together with known structure information of entrance and exit channels nuclei and reaction dynamics. These calculations well reproduce, in the whole energy range, one-and two-neutron transfer channels in shape and magnitude.
