Noise correlation and decorrelation in arrays of bolometric detectors

Abstract

Bolometers are phonon mediated detectors used in particle physics experiments to search for rare processes, such as neutrinoless double beta decay and dark matter interactions. They feature an excellent energy resolution, which is a few keV over an energy range extending from a few keV up to several MeV. Nevertheless the resolution can be limited by the noise induced by vibrations of the mechanical apparatus. In arrays of bolometers part of this noise is correlated among different detectors and can be removed using a multichannel decorrelation algorithm. In this paper we present a decorrelation method and its application to data from the CUORICINO experiment, an array of 62 TeO2 bolometers.
