Moreover, by exploiting Multiple Coulomb Scattering and emulsion ionization measurements, one can obtain accurate measurements of the particle momenta.
The so-called net-scan method [39], also developed in Nagoya, eventually allowed for the reconstruction of tracks by associating all detected track segments independently of their angle and allowed complete event reconstruction [40], momentum determination by Multiple Coulomb Scattering [41, 42] and electron identification by shower analysis [43, 44].
Once one or more vertices are found one can exploit all the rich information stored in the emulsions for a Multiple Coulomb Scattering (MCS) analysis (for track momentum determination) or for the search of electron- or gamma-induced downstream showers.
