The mass composition of cosmic rays above 1 EeV inferred using the spread in arrival times of air shower particles

The sources of ultra high energy cosmic rays (UHECRS) have remained undetected for over half a century. Identifying these sources could be made easier by measuring the charge and thus mass of UHECRs, as this would allow for corrections in their arrival directions due to deflections introduced by intervening magnetic fields to take place. The aim of this thesis is to derive a parameter which can be used as a surrogate for depth )f maximum in the data obtained using the surface array of the Auger Observatory for the measurement of the mass composition of UHECRs.
