Abstract

The International Linear Collider (ILC) is intended to be a new high precision electron-positron collider operating at the TeV scale. The studies detailed within this thesis deal primarily with the development of Monolithic Active Pixel Sensors (MAPS) which could be used as the sensitive component of an ILC Electromagnetic Calorimeter (ECAL). These include simulations of a MAPS ECAL to investigate pixel saturation as a function of reset time, and energy resolution for single electrons. The energy resolutionσ (E)/E was found to be (0.1147±0.0004)/E\(^{1/2}\)(GeV\(^{1/2}\)). The remaining studies describe part of the calibration process for prototype MAPS sensors and how those sensors were used to characterise the response of MAPS pixels to a 120 GeV pion beam. This resulted in a measurement of the MIP (Minimum Ionising Particle) efficiency of MAPS pixels of 75% to 95% with some variation due to the properties of the epitaxial layer.
