A Study of Minimum Bias Events

This note describes the methods developed for the measurement of the properties of minimum bias events during low luminosity running using the ATLAS detector. These methods aim to reconstruct the inclusive pseudorapidity and transverse momentum distributions of charged particles with $p_T > 150$ \MeV\ produced from 14 TeV pp collisions. The triggers used to record minimum bias events are described and their acceptances evaluated. An analysis to measure the inclusive distributions is presented and the systematic uncertainties discussed. Finally, there is an overview of future physics studies with minimum bias samples.
