Abstract

The MAPS technology is considered as a possible choice for the ILC Vertex Detector. Test results of MIMOSA-5 sensors indicate that the pixel multiplicity and the single point resolution depend significantly on the incident particle angle. We propose a simple model describing charge distribution in the detector, which can be used for detailed simulation of the Vertex Detector response. Good agreement with beam test data is obtained. A new class for Track Detailed Simulation (TDS) has been developed and implemented in the EUTelescope software framework.
