摘要

The electromagnetic calorimeter of the AMS-02 experiment is a 3-dimensional sampling calorimeter, made of lead and scintillating fibers. Taking advantage of the fine granularity of the detector, several methods to characterize the electromagnetic shower development have been established, using the information on the lateral and longitudinal shower shape. The reconstruction of the shower axis impacts the identification of leptons and the rejection of protons as well as the identification of the arrival direction of the incoming particles, that is crucial for photon physics. The shower characterization technique and three methods to reconstruct the shower axis will be described, and their performance shown.
