Data analysis of FoCal at 244 GeV using the Hough transform and longitudinal profiles

Abstract

The FoCal prototype detector is a prototype digital sampling calorimeter. In 2014 data was taken from the SPS accelerator at CERN at 244 GeV, consisting of electrons, positrons and hadrons. This thesis analyses that data. By looking at the longitudinal profiles of events, it is concluded that the length of a shower can be used to distinguish between partial and full showers. The Hough transform is used to find the position of incoming particles, it is not succesful in finding secondary tracks.
