Thermal Response Analysis on the Three Towers Detector
The bolometer model we have developed is able to describe the main features of the response function of CUORE bolometers. The TR algorithm, based only on measurable parameters, proved to be a powerful tool to remove the unwanted non-regularities of the response function, but still it is not perfect. The rise time behavior is not fully understood as well as there is a small residual correlation between amplitude and baseline, compatible with the uncertainty on the parameters entering the model. Without this residual drift the proposed analysis could produce better results compared to the standard analysis that suffers from heater instabilities. Moreover, being the pulse shape less dependent on energy, the pulse shape discrimination, a topic we will not cover, becomes simpler. The correctness of the model is also enhanced by the fact that the TR data are closer to a linear calibration than the raw data.
