The aim of BINGO is the development of a technology capable of investigating the Majorana nature of neutrino with unprecedented precision, down to a sensitivity of a few meV to the Majorana neutrino mass.
The first mini nylon assembly. Two Li2MoO4 crystals are fixed using nylon wire and Teflon pieces. Each detector is facing a square light detector.
Several tests have been carried out validate the final mini-BINGO assembly. As a first test, two 2*2*2 cm^3 Li2MoO4 crystals held and fixed using a nylon wire was carries out. The results have shown very promising results. In fact, we had a very good sensitivity, energy resolution and baseline noise. In addition, a test was performed on ZnWO and BGO to confirm the light yield and radioactive contamination to choose the most proper scintillator as a veto for the mini-BINGO assembly.
