Description
Monolithic CMOS sensors have found their way through imaging technologies into High Energy Physics thanks to multiple advantages in particle detection. Their main characteristic is the integration of an active sensor and readout in a single chip, which provides a reduction in production effort, costs and material. The Tangerine project aims to develop the next generation of silicon pixel sensors intended as reference detectors in test beam measurements. The goal is to achieve excellent time and spatial resolution using a 65 nm CMOS imaging technology with a small collection electrode. It offers a significant improvement in the logic density of the pixels, the power consumption, the material budget and the S/N in comparison to previously studied technologies. In virtue of this, the first sensor is envisioned to potentially be used as a telescope in the DESY test beam facility. Both device (TCAD) and Monte Carlo simulations (Allpix$^2$) are needed to develop the understanding of this technology and provide important insight into performance parameters of the sensor, which can be tested afterwards in laboratory and test beam experiments. This contribution will present the latest developments in device simulation results of a 65 nm CMOS sensor with a small collection electrode.
