Resolution and t-spectrum for the ALFA detector

Abstract

My report as Summer Student is in two parts. In the first part I report about my attendance to the run of the ALFA detector to test different collimation schemas and find a new way to get rid of the background. The second part is about the measurement of the resolution of the ALFA detector and comparing the real data with the Monte-Carlo (MC) simulations. First of all I tried to be more familiar with ROOT, worked on understanding the code used to access to the data in the trees inside the Ntuples, plotting histograms,… This was done using old Ntuples which contain MC data
