CUPID is a proposed future tonne-scale bolometric neutrino-less double beta decay (0νββ) experiment to probe the Majorana nature of neutrinos and discover lepton number violation in the so-called inverted hierarchy region of the neutrino mass. In order to improve the sensitivity with respect to the current bolometric experiments, the source mass must be increased and the backgrounds in the region...
We present the first prototype of a custom Data Acquisition System for bolometer and scintillating bolometer detectors. It consists of a board controlled by a Cortex M3 microcontroller coupled with a 8 channels Sigma/Delta 24 bit ADC. The large number of bits allows having at the same time a high dynamic and a high resolution at low threshold, in order to separate very low energy events. Each board...
In this work we present the first part of the Power Supply System for the CUORE and LUCIFER arrays of bolometric detectors. It consists of an AC/DC (0 ∶ 60 V output) commercial supply voltage followed by a system composed of DC/DC modules. Every DC/DC module (48 V input, ±15 V output) is laid-out on a 2 layers 220×236 mm2 PCB (standard Eurocard). Each module has 3 independent configurable output voltages...
