Simulations and Test Beam Results of a MAPS in a 65 nm CMOS Imaging Technology — •Adriana Simancas for the Tangerine collaboration — Deutsches Elektronen-Synchrotron, Hamburg, Deutschland — Universität Bonn, Bonn, Deutschland

Monolithic CMOS sensors produced in a 65 nm imaging technology are being investigated for an application in particle physics for the first time. Their main characteristic is the integration of an active sensor and readout circuit in the same silicon wafer, which provides a reduction in material budget. Compared to the previously investigated 180 nm process, the 65 nm technology offers a significant improvement in the logic density of the pixels. The small collection electrode sensor is characterized by a low input capacitance, granting a high signal to noise ratio and a low power consumption. The Tangerine Project aims to use this technology for vertex detectors at future lepton colliders. TCAD Device and Monte Carlo simulations are used to develop an understanding of the sensor technology and provide important insight into performance parameters of the sensor. Testing prototypes in laboratory and test beam facilities allows to study their charge collection, spatial resolution and efficiency. Combining results from all these studies it is possible to optimize the sensor layout. This contribution will present the first comparison of simulation results to test beam data of a 65 nm CMOS sensor with a small collection electrode.
