The IRFU contribution to the ALICE experiment focused on the largest tracking chambers of the muon spectrometer, which measures the μ+μ- pairs coming from the decay of the ϒ and J/ψ resonances.
Introduction
The muon spectrometer, which covers the polar angular range between 2° and 9°, consists of a front absorber, five tracking stations with the third one located inside a warm dipole, an iron wall and triggering chambers.
