Summary: | The Extreme Energy Events (EEE) Collaboration is fully involved in an
ecological transition. The use of the standard gas mixture,
\ce{C_{2}H_{2}F_{4}}+ \ce{SF_{6}}, has stopped in favor of an alternative green
mixture based on \ce{C_{3}H_{2}F_{4}} with the addition of He or \ce{CO_{2}}.
The choise of these new mixtures is motivated by the significant lower Global
Warming Potential (GWP) to reduce the emission of gases potentially
contributing to the greenhouse effect. The EEE experiment consists of 61 muon
telescopes based on Multigap Resistive Plate Chambers (MRPCs), each telescope
composed of 3 chambers filled with gas. Several EEE detectors are today
completely fluxed with the new ecological mixture. This contribution will
report recent results about the telescope performance obtained from studies
with the eco-friendly alternative mixture carried out in the last years. |
