✦ Synopsis

Neutron-induced effects have been studied in Monolithic Active Pixel Sensors (MAPS) designed at CEA/Saclay and IPHC/ Strasbourg. 55 Fe X-rays were used to assess the detection capabilities. The pedestals and the temporal noise were studied together with the charge collection efficiency. The results are compared to estimations of the deep trap introduction rates. For neutron-integrated fluxes up to 10 12 cm À2 , these MAPS are weakly degraded by irradiation.

The monolithic active pixel sensors (MAPS) using a standard dual-well CMOS process on lightly doped epitaxial wafers have demonstrated competitive tracking and imaging performance for minimum ionizing particles (MIP) detection. In this paper, a Gaussian-doped substrate is proposed to improve the per
