The Silicon Vertex Detector (SVD), with its four double-sided silicon strip sensor layers, is one of the two vertex sub-detectors of Belle II operating at SuperKEKB collider (KEK, Japan). Since 2019 and the start of the data taking, the SVD has demonstrated a reliable and highly efficient operation, even running in an environment with harsh beam backgrounds that are induced by the world's...

Belle II is the next generation B Factory experiment operating at the SuperKEKB accelerator complex at KEK in Tsukuba, Japan. It is expected to collect 50 ab-1 of data, with a target instantaneous luminosity of $\rm{6.5 \times 10^{35} cm^{-2}s^{-1}}$, which is about 30 times larger than its predecessor.
The Silicon Vertex Detector (SVD) consists of four layers of double-sided silicon...

CERN’s ATLAS and CMS experiments were designed with prompt and standard model particles in mind. The track-trigger upgrades planned for the High Luminosity LHC open up the possibility to trigger on long-lived and unconventional signatures directly. To maximize sensitivity for these challenging signatures, we study the efficiency of hypothetical hardware level track triggering algorithms. We...

The ITkPixV1 chip is the pre-production pixel readout chip for the Phase-2 Upgrade of the ATLAS experiment at the HL-LHC. The harsh environment of HL-LHC, including a peak luminosity of 5x10^34cm-2s-1 and an estimated total ionising dose (TID) of 1 Grad throughout its lifetime is placing strong requirements on the radiation tolerance of the chip. This contribution outlines investigations into...

The FASER experiment at CERN takes advantage of the enormous flux of hadrons produced at zero-angle at the ATLAS interaction point to perform the first search for low-mass, Long Lived Particles (LLPs) at the LHC.

The ALICE upgrade planned for the LHC Long Shutdown 3 aims to replace the three innermost of the current Inner Tracking System (ITS) with a new silicon detector based on wafer-scale, ultra-thin, truly cylindrical Monolithic Active Pixel Sensors built with 65 nm technology (ITS3).

Recent developments in semiconductor pixel detectors allow for a new generation of positron-emission tomography (PET) scanners that, in combination with advanced image reconstruction algorithms, will allow for a few hundred micron spatial resolutions. Such novel scanners will pioneer ultra-high resolution molecular-imaging, a field that is expected to have an enormous impact in several medical...

The aim of the MONOLITH H2020 ERC Advanced project is to develop fully monolithic highly granular pixel sensors with picosecond time stamping capabilities. To reach a picosecond precise sensor response, a thin gain layer has been implemented deep inside a high-resistivity epitaxial layer. By moving the gain layer away from the pixel implantation, the pixel size can be reduced down to 50 µm,...

The need for 4D tracking and Ultra-Fast Silicon Detectors is a result of the expected pile-up at the High-Luminosity LHC General-Purpose Detectors. To fully reconstruct events along the beam line where post-collision reconstruction with 3D detectors is insufficient, timing information is added to the spatial measurements to disentangle overlapping events. Track timing resolution of the order...
