We present an innovative charge detector with high resolution and wide dynamic range designed to fulfill the requirements of a monitoring system for a high energy ion beam. The detector prototype, constructed using Si planar diodes and a custom readout electronics, underwent extensive testing during HERD and AMS beam tests at CERN SPS facilities. Initial testing showcased the detector's...

The DarkSide-20k experiment, currently under construction at the Gran Sasso Laboratory (LNGS), represents a significant advancement in the field of direct Dark Matter (DM) detection. Utilizing a liquid argon dual-phase time projection chamber (LArTPC) with a 20-tonne fiducial mass, DarkSide-20k is designed to extend the sensitivity limits in the search for Weakly Interacting Massive Particles...

This talk will present the performance of the CMS experiment pixel detector during the LHC Run 3. Hit detection efficiency, collected charge and hit resolution will be presented as determined at the end of 2024 and as a function of the integrated luminosity delivered by the accelerator. Other important results, such as the Lorentz Angle determination, will be presented together with the high...

A Muon Collider with the centre-of-mass energy of 10 TeV is actively studied as a successor of the LHC thanks to its unique combination of high energy reach, clean final state and low environmental footprint. Very low level of synchrotron radiation allows to accelerate muons to multi-TeV energies in a compact ring with minimal energy losses, allowing to reach the discovery potential of the...

environments with fluences exceeding $1\times10^{17}$ 1-MeV $n_{eq}/cm^2$. Presently available silicon sensors can operate efficiently up to fluences of the order of some $10^{16}$ 1-MeV $n_{eq}/cm^2$. Therefore, novel sensors and readout electronics must be devised.
Within this framework, state-of-the-art Technology CAD... -

We report on the characterization of 3D columnar-electrode sensors featuring 55 μm-pitch square and hexagonal pixel cells, evaluated with the Two-Photon Absorption Transient Current Technique (TPA-TCT) using the SSD laser facility at CERN. These sensors, manufactured at IMB-CNM, are double-sided n-in-p diodes with a thickness of 285 μm. The study provides detailed maps of the electric field...

We present the 3D scans of the latest 3D columnar silicon sensor technology, manufactured at the CNM-IBM (RD50 Common project). Double Sided Double Type Technology is studied. Hexagon structures ( 5x5 array of 3D Si cells) are compared to Quadratic structures (10x10 array of 3D Si cells). Timing study is performed using TCT set up at ELI (both SPA where we exploited two wavelengths and TPA...

SINTEF MiNaLab is currently producing part of the 3D pixel sensors for the ATLAS ITk upgrade. Given the number of sensors requested and the complexity of the technology, the production has been split into two 24-wafer batches (Run-7 and Run-8). The two batches have been carefully scheduled to avoid conflicts in the clean room. Both batches use the common sensor layout for RD53B sensors in...

The High Luminosity upgrade of the Large Hadron Collider (HL-LHC) will demand the ATLAS detector to face an increased instantaneous luminosity up to $7.5\times 10^{34} cm^{−2} s^{−1}$ and an average of 200 proton-proton collisions per bunch-crossing. To cope with this challenge, the present ATLAS Inner Detector will be completely replaced with a new silicon-based Inner Tracker (ITk), made of a...

Low Gain Avalanche Detectors (LGADs) can operate in single particle counting mode directly in proton beams. These detectors are radiation hard, allowing operation under therapeutic beam fluences for extended periods. With timing resolution below 50 ps, LGADs can provide precise timing measurements of individual particles. This study examines the use of LGADs as particle counters for beam...

Low Gain Avalanche Diodes(LGADs) are prime candidates for high resolution timing applications in High Energy Physics, Nuclear science, and other fields. Over the course of their lifetime, these sensors are required to withstand enormous amounts of radiation (> 10$^{15}$ neq/cm$^2$) while maintaining acceptable performances at hadron colliders. Particles interacting with highly biased sensors...

The response of Low Gain Avalanche Diodes (LGADs), a type of thin silicon detector with internal gain, to X-rays of energies between 6-16 keV was characterized at the SLAC light source (SSRL). The utilized beamline at SSRL was 7-2, with a nominal beam size of 30 μm, repetition rate of 500 MHz, and with an energy dispersion ∆E/E of 10−4. Multi-channel LGADs, AC-LGADs, and TI-LGADs of different...

Low Gain Avalanche Diodes (LGADs) are ultra-fast silicon detectors that allow the simultaneous measurement of an ion’s position and time-of-arrival with a precision better than 100µm and 100ps, respectively. This excellent 4D-tracking capability enables the reconstruction of single-particle tracks even in high-luminosity environments, such as those encountered in high-energy physics...

DC-RSDs are an evolution of the AC-coupled RSD sensors, commonly called AC-LGAD. The DC-RSD design is characterized by the direct contact of the metal electrode with the n+ resistive layer and by the presence of trenches to avoid uncontrolled signal sharing among pixels.

Recent advantages in detector production have facilitated the manufacture of pixelated 4H-SiC detectors, which can be an alternative to silicon ones especially in the harsh radiation environment, or in the environment with high temperatures, where such sensors profit from their higher band gap. Moreover, thanks to an elastic scattering cross-section of carbon for fast neutrons the SiC sensors...
