Description
BINGO is a technology demonstrator dedicated to the development of innovative background reduction techniques for cryogenic calorimetric searches for neutrinoless double beta decay ($0\nu\beta\beta$). Targeting a background index of $10^{-5}$ counts/(keV·kg·yr), BINGO aims to establish a path toward a nearly background-free $0\nu\beta\beta$ experiment based on a tonne-scale deployment of $^{100}$Mo and $^{130}$Te isotopes.
Key design strategies include: (i) a novel detector architecture that reduces the exposed surface area of passive materials in the detector array by more than an order of magnitude; (ii) a tightly packed array of BGO scintillators operating as an active cryogenic veto system; and (iii) enhanced Neganov-Trofimov-Luke light detectors to suppress pile-up background for $^{100}$Mo and enable alpha-beta discrimination in $^{130}$TeO$_2$.
A dedicated cryogenic infrastructure has been installed and validated at the Modane Underground Laboratory (LSM), providing the necessary environment for low-background operations. Data-taking with prototype detectors is currently ongoing to validate the technological solutions and optimize the final design. A first physics run with MINI-BINGO is foreseen for 2026.
We present the technical design of these concepts, results from prototype technologies in proof-of-concept measurements, initial preliminary results from Modane, and Geant4-based projections of the expected impact of these improvements in a CUORE/CUPID-scale experiment.
