Future new high luminosity colliders will require exeptionally radiation hard detectors, in particular those that will be closer to the interaction regions, i.e. tracking and vertexing detectors. The TimeSPOT R&D project has developed a new family of 3D silicon pixel sensors with 55 μm pitch that have shown an outstanding time resolution of about 10 ps thanks to their new “trench” design. In...
The Belle II experiment at SuperKEKB operates at a record luminosity of $5.1 \times 10^{34}~\mathrm{cm}^{-2}~\mathrm{s}^{-1}$, with plans to reach $6 \times 10^{35}~\mathrm{cm}^{-2}~\mathrm{s}^{-1}$. To handle higher backgrounds and improve tracking precision, an upgraded vertex detector (VTX) is needed. The new VTX will feature 5-6 layers equipped with OBELIX, a depleted monolithic active...
Monolithic CMOS silicon sensors represent an important innovation for high-energy physics experiments due to their cheaper production and assembly cost compared to hybrid ones, where the electronics and the sensor are produced on different silicon substrates and later connected using bonding techniques. However, concerning the time resolution, today the most mature and high-performance...
The ATLAS Experiment is building a complete new Silicon tracker, so called ITk, to face the challenges imposed by the HL-LHC phase in terms of instantaneous and integrated luminosity. The tracker will have pixel detectors in the innermost part and strip detectors in the outermost part. To deal with the high fluence, the innermost layer of the pixel detector will be instrumented by 3D...
The INFN ARCADIA collaboration developed a fully depleted MAPS sensor as technology demonstrator aimed at next-generation experiments and applications in both e the space and medical field. Realized in LFoundry 110nm technology node, the ARCADIA sensor embeds a custom backside process to extend the depleted volume to the entire high-resistivity substrate, down to nanometers from the back...
Silicon microstrip (Si-µstrip) sensors are employed in most of current space detector tracking systems for charged cosmic-rays, such as the DAMPE satellite detector or the AMS-02 detector onboard the ISS. As they allow for large-area coverage with contained electronic channels and power consumptions, they are ideal sensors for high-energy physics applications in space-borne instrumentation,...
Resistive Silicon Detectors (AC-LGAD - RSD, DC-RSD) offer very good spatial (10-20 microns) and temporal resolution (30 - 40 ps) using large pixels (300 - 500 microns). RSDs are very thin, have 100% fill factor, and are radiation tolerant up to 1E15 n/cm2.
Given their low electrode density (for equal spatial resolution about a factor of 100 less than standard design), RSDs are ideal for low...
State-of-the-art silicon sensors are able to operate efficiently up to
fluences of 1E16/cm. Future frontier accelerators envisage the use of
tracking detectors in environments with fluences exceeding 1E17/cm.
The possible solution to overcome the present limit in radiation tolerance
is to exploit the recently observed saturation of radiation damage effects
on silicon, together with the...
As the ECFA detector research and development roadmap outlines, "revolutionary improvements in the performance of solid-state detectors are essential to meet the requirements of future experiments." In this context, Technology Computer-Aided Design (TCAD) is a highly valuable tool that can reduce costs and development time by providing a comprehensive understanding of the devices' physical...
Timepix4 is the latest application-specific integrated circuit (ASIC) developed by the Medipix4 international Collaboration at CERN. It features a 448x512 pixel matrix with a 55 μm pitch, designed for compatibility with a wide range of semiconductor sensors. This adaptability allows for optimization in various applications, including X-ray spectroscopy, high-energy particle detection, and...
This work presents a novel signal readout and data processing system based on a 32-bit ARM microcontroller for spectroscopic applications.
Previous attempts to develop microcontroller-based spectroscopy systems have often struggled with limitations such as low performance and high dead time, making them impractical for real-world use. This work introduces a highly customizable, full-stack...
Integrating and packaging silicon detectors can be challenging due to constraints such as size, material compatibility, and system complexity. Choosing the right packaging solution is crucial for simplifying detector integration in custom applications.
This work presents an alternative approach developed and used in our laboratories for silicon detector packaging, where the detector is...
Transient High-Energy Sky and Early Universe Surveyor (THESEUS) is a
multi-instrument space mission concept candidate under European Space Agency (ESA) M7 Phase-Assessment study for medium size missions with an intended launch in 2037. The main goals of this mission include exploring the early universe by identifying and localising Gamma Ray Bursts (GRBs) at high redshifts (potentially up to...
The SiliciSpazio INFN project plans to evaluate LGAD and MAPS detectors for space applications. In parallel, the project aims to advance the packaging of such detectors, testing ultra-thin flexible solutions that could drastically improve payload miniaturisation and the design of the space electronics and harnesses. The packaging will involve the TAB bonding method, which provides higher...
The ATLAS experiment at CERN is getting more and more ready to face the High-Luminosity era of the Large Hadron Collider, that will set harsher conditions in terms of radiation, luminosity and data stream for the ATLAS Detector. One of the key detector upgrade is the new all-silicion Inner Tracker, the ITk, that the ATLAS Collaboration is building to replace the ATLAS Inner Detector for the...
