Timing studies of MAPS in 65 nm imaging process — •Manuel Alejandro Del Rio Viera — Deutsches Elektronen-Synchrotron (DESY) — Rhenish Friedrich Wilhelm University of Bonn

The goal of the TANGERINE project is to develop the next generation of monolithic silicon pixel detectors using a 65 nm CMOS imaging process, which offers a higher logic density and overall lower power consumption compared to currently utilized feature sizes. The Analogue Pixel Test Structure (APTS) are sensors designed and developed by ALICE with readout boards developed by CERN EP R&D using a 65 nm imaging process to study the capabilities of this technology. In order to study the timing capabilities, the sensor is tested at the DESY-II test beam facility. For each hit produced by an incident particle, the analogue signal output is recorded using an oscilloscope for offline analysis and track reconstruction. From this analysis, relevant timing parameters are compared with studies obtained through Technology Computer-Aided Design (TCAD) and Monte Carlo (MC) simulations. In this contribution, the sensor and setup, results obtained at the DESY-II Test Beam facility, laboratory characterization measurements using Fe-55, and a comparison with simulations will be presented.
