The third Workshop of the NuMass series (The Future of Neutrino Mass Measurements: Terrestrial, Astrophysical, and Cosmological Measurements in the Next Decade: NuMass 2013) was held at Dipartimento di Fisica G. Occhialini, University of Milano-Bicoc
ca in Milano, Italy, on 4-7 February 2013. The goal of this international workshop was to review the status and future of direct and indirect neutrino mass measurements in the laboratory as well as from astrophysical and cosmological observations. This paper collects most of the contributions presented during the Workshop.
The external shell of the CUORE cryostat is a large cryogen-free system designed to host the dilution refrigerator and the bolometers of the CUORE experiment in a low radioactivity environment. The three vessels that form the outer shell were produce
d and delivered to the Gran Sasso underground Laboratories in July 2012. In this paper, we describe the production techniques and the validation tests done at the production site in 2012.
$TeO_2$ crystals are used as bolometers in experiments searching for Double Beta Decay without emission of neutrinos. One of the most important issues in this extremely delicate kind of experiments is the characterization of the background. The knowl
edge of the response to $alpha$ particles in the energy range where the signal is expected is therefore a must. In this paper we report the results on the response function of a $TeO_2$ bolometer to $alpha$s emitted by $^{147}$Sm dissolved in the crystal at the growth phase. A Quenching Factor of ($1.0076pm 0.0005$) is found, independent of the temperature in the investigated range. The energy resolution on $alpha$ peaks shows a standard calorimeter energy dependence: $sigma; [rm{keV}] = (0.56 pm 0.02) oplus (0.010 pm 0.002)sqrt{E[rm{keV}]} $. Signal pulses show no difference between $alpha$ and $betagamma$ particles
