Abstract
Charged-particle pseudorapidity density measurements help in understanding particle production mechanisms in high-energy hadronic collisions, from proton-proton to heavy-ion systems. Performing such measurements at forward rapidity, in particular, allows one to access the details of the phenomena associated with particle production closer to the fragmentation region of the colliding nuclei. In ALICE, this measurement will be performed in LHC Run 3 exploiting the Muon Forward Tracker (MFT), a newly installed detector extending the inner tracking pseudorapidity coverage of ALICE in the range $ - 3.6<\eta< - 2.5$. The performance of the ALICE MFT will be presented for the pilot beam data taking of October 2021 for proton-proton collisions at $\sqrt{s}$
= 900 GeV, along with a preliminary result of charged-particle pseudorapidity density at midrapidity obtained with the newly installed Inner Tracking System (ITS2).
