Detectors at future linear colliders will require unprecedented energy and position resolutions. Two CMOS Monolithic Active Pixel Sensor (MAPS) concepts, TPAC and FORTIS, have been designed to study the issues involved in achieving these requirements. One application proposes MAPS as the active layer of a sampling electromagnetic calorimeter, allowing high granularity calorimeter systems which can utilise particle flow techniques. The TPAC sensors were developed to study this application. These sensors were made with a new fabrication technology and have demonstrated a significantly improved MIP effciency compared to sensors made using the standard fabrication technology. The sensors have been tested at CERN and DESY for their response to positrons, pions and electromagnetic showers. TPAC sensors have also been irradiated using x-rays to investigate their radiation hardness for use in vertex and tracking detectors. A noise increase ≤7% has been observed at 1 Mrad.
