Speaker
Description
Recently, considerable interest has arisen in the development of crystal scintillators of the family of metal hexachlorides Cs$_2$MCl$ _6$ (M = Hf or Zr) thanks to their exceptional properties: a high light yield (up to 40000 photons/MeV), good linearity in the energy response, excellent energy resolution ($<3.5\%$ at 662 keV in the best configuration) and excellent pulse shape discrimination (PSD) between $\beta$($\gamma$) and $\alpha$ particles. In particular, we present here a first measurement using two Cs$_2$ZrCl$_6$ crystal scintillators ($\oslash$ $21\times 21$ mm$^2$ each) which has been performed at the DAMA/CRYS setup of LNGS. These crystals have been studied in terms of their chemical purity and residual radioactive contaminants, scintillation and PSD performances. Preliminary studies on single beta decays of $^{96}$Zr and double beta decays in isotopes of $^{94,96}$Zr have also been carried out and shown.
