Description
BINGO is a prototype experiment to demonstrate a path towards a nearly background free tonne-scale cryogenic $0\nu\beta\beta$ experiment with O(10000) detectors with the isotopes $^{100}$Mo and $^{130}$Te. The major design aspects to achieve this goal are (1) a novel detector assembly reducing the exposed surface area of un-instrumented (passive) materials in the detector array by more than an order of magnitude, (2) an additional tightly packed array of BGO scintillators that surrounds the detector array and acts as active cryogenic veto system and (3) the use of Neganov-Trofimov-Luke based light detectors that help mitigate the pile-up background for Mo-100 and ensure the alpha-beta discrimination in Te-130. In this talk we will describe the technical design of these concepts for the BINGO demonstrator and recent individual proof-of concept validations of the technologies. We will also provide an initial outlook on the effect of these improvements in a CUORE/CUPID size experiment.
