Modelling the shape of thermal pulses from low temperature detectors

Low temperature detectors are nowadays a technology widely used for rare events studies, such as the search for dark matter candidates and neutrino-less double beta decay. The convolution of the thermal and electrical response of these detectors results in pulses with different shapes depending on the materials, dimensions and operating conditions of the thermal sensors. It appears crucial to obtain a good description of the pulse shape, in order to possibly understand the several contributions in the thermal pulse formation. In this work, we present a general approach which allows us to model the shape of thermal pulses from different low temperature detectors.
