The Extreme Energy Events (EEE) Laboratory is located on floor -1, room 403, of the historic building that houses the Enrico Fermi Research Center (CREF).

The telescope consists of three Multigap Resistive Plate Chamber (MRPC) detectors, which make it possible to reconstruct the point of passage of subnuclear particles with a spatial resolution of cm² and a temporal resolution of about 250 ps. The laboratory also includes a custom weather station based on Arduino, two DC power supplies, two computers, and a Tektronix WaveRunner 8254M oscilloscope (2.5 GHz, 40 GS/s).

The telescope is part of a network of 50 telescopes installed throughout Italy. It is possible to correlate the data from detected muons with local environmental parameters or, through GPS synchronization, to study correlations between events over large distances. The transformation of the tracking and coincidence algorithms for muons belonging to the same shower is currently being studied using the Quadratic Unconstrained Binary Optimization (QUBO) approach, in order to perform certain analyses using a photonic computer currently under development at CREF. At the same time, the use of Artificial Intelligence (AI) systems is being designed for the monitoring tools that oversee the operation of the network.

In the coming years, the laboratory will be used for:

– efficiency tests of particle detectors based on Silicon Photomultipliers;

– assembly and testing of detectors in the new experimental area on floor -1 of the building;

– construction of cloud chamber detectors for CREF third-mission activities;

– expansion of the outreach facilities, including the installation of monitors, posters, etc.

An expansion of the experimental areas on floor -1 is also planned. Within these areas, a dedicated space will be used for the assembly of compact, transportable detectors aimed at extending the EEE network.
