• Abstract The paper describes the matching of tracks in a nuclear emulsion detector interleaved with scintillating optical fiber (SciFi) planes. This technology is planned to be used in the Scattering and Neutrino Detector (SND) of the new experiment SHiP (Search for Hidden Particles) being developed in CERN. The experiment SHiP aimed on the search of very weakly interacting particles in the poorly studied region of the particle masses below 10 GeV will be installed in a beam dump facility at the Super Proton Synchrotron (SPS). The SND detector is aimed to provide temporal and spatial analysis of the particle showers and isolated tracks to separate and reconstruct events in nuclear emulsion. SND design includes emulsion cloud chamber (ECC) and SciFi tracker. Motivation for using the combination of ECC and SciFi is to obtain the “real-time” information for the prompt and high-accuracy event analysis. The algorithm presented in the article provides a track matching accuracy not less than 50 μm with an efficiency of (89±8)%.
