Description
Neutrinoless double beta decay is a decay mode in which two neutrons are converted
in two protons and two electrons are emitted. This process can take place only if
neutrino is its own antiparticle. Thus it is a unique tool to probe the Majorana
nature of the neutrino. CUORE (Cryogenic Underground Observatory for Rare Events)
aims to detect neutrinoless double beta decay of the $^{130}\text{Te} $. The CUORE experiment,
currently in its construction phase, will consist of an array of 998 $\text{TeO}_{2}$
bolometers and will be operated at 10 mK temperature in Laboratori Nazionali del
Gran Sasso.
CUORE-0, the first tower of CUORE, an array of 52 $\text{TeO}_{2}$ crystals, has been operated
in the last two years as a full CUORE prototype.
The large amount of data collected by CUORE-0 makes it ideal to study in detail
the performances of bolometric detectors.
The goal of my analysis is to study of CUORE-0 detectors response and behaviour.
The bolometric technique is based on the measurement of the energy released by an
interacting particle converted in to phonons. Despite the simple model of an ideal
bolometer the actual response is much more complex. Finding the different
components of the CUORE-0 pulses and correlating them to physics
parameters will allow a better understanding of the detectors and possible
improvements of the response. In my analysis I first defined a set of variables to
describe the pulse shape. Then I started the study of correlation between pulse
shape parameters and detector response.
