Resolution of a Forward Calorimeter prototype

Abstract

To study the properties of high energy reactions where photons and partons are involved, the ALICE-FoCal collaboration is developing a forward calorimeter to measure photons in electromagnetic showers. These showers occur when a highly energetic photon, electron or positron interacts with matter and it decays via pair production or brehmsstrahlung. We are interested in showers that are not initiated by neutral pion decay but ones with direct photons. The aim of this thesis is to determine the resolution of the forward calorimeter prototype in detecting these 'pure' electromagnetic showers.
