During the second long shutdown of the Large Hadron Collider at CERN, the LHCb experiment has been upgraded and the new detector is currently operating at the LHC. The Vertex Locator (VELO) is the detector surrounding the interaction region of the LHCb experiment, responsible of reconstructing the proton-proton collision (primary vertices) as well as the decay vertices of long-lived particles...
In the high-luminosity era of the Large Hadron Collider, the instantaneous luminosity is expected to reach unprecedented values, resulting in up to 200 proton-proton interactions in a typical bunch crossing. To cope with the resulting increase in occupancy, bandwidth and radiation damage, the ATLAS Inner Detector will be replaced by an all-silicon system, the Inner Tracker (ITk). The innermost...
ATLAS is currently preparing for the HL-LHC upgrade, with an all-silicon Inner Tracker (ITk) that will replace the current Inner Detector. The ITk will feature a pixel detector surrounded by a strip detector, with the strip system consisting of 4 barrel layers and 6 endcap disks. After completion of final design reviews in key areas, such as Sensors, Modules, Front-End electronics and ASICs, a...
The Compact Muon Solenoid (CMS) detector at the CERN Large Hadron Collider (LHC) is undergoing an extensive Phase 2 upgrade program to prepare for the challenging conditions of the High-Luminosity LHC (HL-LHC). A new timing detector for CMS will measure minimum ionizing particles (MIPs) with a time resolution of ~30-40 ps for MIP signals at a rate of 2.5 Mhit/s per channel at the beginning of...
The SuperKEKB collider will undergo a major upgrade at the end of the decade to reach the target luminosity of 6 10^35 cm-2 s-1, offering the opportunity to install a new pixelated vertex detector (VTX) for the Belle II experiment. The VTX will be more robust against the expected higher level of machine background and more performant in terms of standalone track finding efficiency.
The VTX...
The MONOLITH H2020 ERC Advanced project aims at producing a high-granularity monolithic silicon pixel detector with picosecond-level time stamping. Such extreme timing exploits fast and low-noise SiGe BiCMOS electronics, and a novel sensor concept: the Picosecond Avalanche Detector (PicoAD).
A prototype without internal gain layer and 100µm pixel pitch was produced in 2022. Lab...
Silicon Photomultipliers are the state-of-the-art technology in single-photon detection with solid-state detectors. Single Photon Avalanche Diodes (SPADs), the key element of SiPMs, have been introduced by CMOS foundries into process design kits, facilitating the development of monolithic SiPMs with custom ASICs. This allows implementing features such as signal digitization, masking,...
We have developed a novel design for a high pixel density position sensitive detector that avoids the use of the analogue circuit for amplification of the signal. The working principle of this novel silicon sensor is based on the change of a binary status when an ionising particle crosses the devices. This mode of operation has multiple advantages, from very high position resolution, low power...
Future hadronic colliders, like FCC-hh, demand efficient tracking detectors in environments with expected fluences exceeding 1 $\times$10 $^{17}$ 1MeV n$_{\mathrm{eq}}$cm$^{-2}$.
Thin Low-Gain Avalanche Diodes (LGADs) emerge as promising candidates for 4D tracking in upcoming experiments, exhibiting precision in timing and tracking capabilities. Their internal signal amplification proves...
Silicon Carbide (SiC) is a semiconductor with a wide, indirect bandgap. It is one of the hardest materials present in nature. The strong bonds determine a large bandgap, implying a high refractive index and a broad transparency over the visible spectrum. Other properties, such as ultraviolet (UV) wavelength absorption, radiation hardness, make this material attractive for alternative...
