The measurement of the total proton-proton cross-section using the luminosity independent method and the ρ parameter at the maximal collision energy of 13.6 TeV or more in Run 3 at CERNs Large Hadron Collider (LHC) requires an upgrade of the existing TOTEM T2 telescopes, which is called the new T2 (nT2). The specifications for nT2 is to provide inelastic event counting with maximal efficiency for data taking in special runs. The nT2 telescope consists of four quarters with each of them having 4 planes of plastic scintillators distributed in circular geometrical shape around the beam pipe on both sides of the CMS experiment and, at a distance of 15 m from the interaction point. The development of the concept was done in cooperation with CERN with the mass-production carried out at HIP. The results of its characterization at the PS and SPS at with muons/pions will be shown.Peer reviewe
