Description
The Tangerine project aims to develop new state-of-the-art high-precision silicon detectors, utilising a novel 65 nm CMOS imaging technology. This technology allows for monolithic sensors containing small pixels with a high logic density, crucial for meeting the requirements at future lepton colliders. The technology is hitherto unused in particle physics applications however, and the Tangerine project aims to develop and test sensors in it, demonstrating its suitability.
The initial goal of the project is to develop a sensor that can be used in test beam telescopes at DESY, providing high spatial and temporal resolutions. The project covers all aspects of sensor R&D, from electronics and sensor design using simulations, to prototype test chip characterisation in labs and at test beams. The sensor design simulations are performed by using a powerful combination of detailed electric field simulations using technology computer-aided design and high-statistics Monte Carlo simulations using the Allpix Squared framework. A simulation approach free from proprietary information has been developed, and results of the simulations compared to measurements of prototypes. Several prototype test chips in a 65 nm CMOS imaging technology have been designed and produced, and successfully operated and tested both in labs and at test beams.
This talk will describe the project, show results from prototype test chips, and describe the developed simulation approach.
