Measurement of the muon flux in the tunnels of Doss Trento hill

In the context of astroparticle physics, nuclear astrophysics and quantum computing projects, it is important identifying underground laboratories where the cosmogenic background is suppressed. Located about 500 m far from the center of Trento (Italy) the Piedicastello tunnels are covered by 100 m limestone rock of the Doss Trento hill. The site exceeds 6000 m2 surface and is currently hosting events, temporary exhibitions, and educational activities. The cosmogenic background was measured in different locations within the Piedicastello tunnels with three portable scintillator telescopes having different geometrical acceptances. The muon flux measured in the deepest part was found to be about two orders of magnitude lower than the surface flux. This preliminary measurement suggests the use of the site as a facility in which a low environmental background is required.
