The HENSA/ANAIS collaboration aims for the precise determination of neutron flux that could affect ANAIS-112, an experiment looking dark matter annual modulation using NaI(Tl) scintillators. In this work, first measurements and Monte Carlo simulations spectrum are reported.

A large number of the presently running neutrino and dark-matter experiments use thallium-doped cesium-iodide CsI[Tl] crystals, sodium-doped CsI[Na] or sodium-iodide NaI[Tl] crystals. In present paper we calculate elastic inelastic cross sections for neutral-current supernova-neutrino scattering off $^{127}\mathrm{I}$ $^{133}\mathrm{Cs}$, relevant using CsI[Tl], CsI[Na], We study also folded wi...

In this paper, we propose a CdZnTe rotating and spinning gamma camera attached with a slit collimator. This imaging system acquires convergent planar integrals of a radioactive distribution. Two analytical image reconstruction algorithms are proposed. Preliminary phantom studies show that our small CdZnTe camera with a slit collimator outperforms a larger NaI(Tl) camera with a pinhole collimato...

ANAIS (Annual Modulation with NaI’s) is an experiment planned to investigate seasonal modulation effects in the signal of galactic WIMPs using up to 107 kg of NaI(Tl) in the Canfranc Underground Laboratory (Spain). A prototype using one single crystal (10.7 kg) is being developed before the installation of the complete experiment; the first results presented here show an average background leve...
