To meet the increasingly demanding performance requirements of future High Energy Physics experiments, ongoing and future Monolithic Active Pixel Sensor (MAPS) developments focus on enhancing key characteristics (such as spatial resolution, timing precision, and energy resolution). Achieving these improvements requires advanced and accurate simulation tools.
For the electrical modeling of...
This contribution outlines the development of PixESL[1], a virtual prototyping framework for pixel detectors based on C++/SystemC. It offers a platform for describing detector ASICs designed for High Energy Physics experiments at a high level of abstraction, with the capability to simulate an electronics system from the output of a framework for semiconductor particle interaction, such as...
The ATLAS ITk-Pixel and ITk-Strip detectors are planned tracker upgrades for the High-Luminosity LHC utilizing n+-in-p silicon sensors. They must withstand severe irradiation over their operational lifetimes, corresponding to fluences of up to 9x10^15 1-MeV neq/cm, with consequences on charge collection efficiencies. To achieve a precise understanding of the expected performance and to...
In the past few months CERN EP-R&D WP1.2 in collaboration with ALICE ITS3 adapted its Monte Carlo simulation methodology to support a lookup based propagation technique : In a first step the pixel is meshed and a fixed amount of electrons are injected in each node and propagated in the ‘standard’ way using TCAD generated electric field, the final state of these electrons is saved. In a second...
MÖNCH is a charge-integrating hybrid pixel detector with a 25 µm pitch. The charge information collected by individual pixel makes is possible to enhance the detector’s spatial resolution under low flux condiftions, either using conventional interpolation or novel machine learning approaches. For this a thorough understanding of the charge transport is essential, especially for machine...
Our research group is developing a novel, ultra-high resolution, Xray sensor for use in medical imaging CT. The sensor is an edge-on deep-silicon sensor and achieves the resolution by performing charge-fitting on the signal from adjacent pixels for single interactions.
In previous comparisons between measurements and simulations it has been noted that the amount of charge sharing is less in...
