An interactive tool for the analysis of nuclear emulsion data

In this paper, we present an interactive tool developed to analyze and display events recorded in nuclear emulsion experiments. Besides providing an excellent way to complement automatic emulsion scanning techniques this program implements a new approach for the complete three-dimensional (3D) analysis of the events. ogram uses information recorded during automatic emulsion scanning procedure and commonly called “video images.” The main features implemented are: automatic full track reconstruction up to wide angles (∼0.8 rad) with efficiency greater than 95%, vertex finding, “kink”’ finding, two-dimensional “microscope” visualization, 3D full view display and analysis. mances were evaluated using a large set of video images containing manually checked neutrino interaction events and preliminary test beam exposure data.
