The MALTA2 sensor is the second prototype in the MALTA family of Depleted Monolithic Active Pixel Sensors, developed using a modified 180 nm CMOS imaging process and optimized for operation in the high-radiation and high hit-rate conditions of future collider experiments. With a matrix of 224 × 512 pixels and a 36.4 $\mu$m pitch, MALTA2 is designed for fast charge collection, low noise, and...

The ALICE experiment will upgrade the innermost three layers of its vertexing detector, the Inner Tracking System (ITS), during the next LHC Long Shutdown (LS3) with a novel, bent, ultra-light MAPS-based tracker. Six wafer-scale sensor chips will be bent into three cylinders, held in place only by carbon foam, leaving no material except for the silicon die in most of the ALICE central barrel...

High-Voltage CMOS (HVCMOS) pixel sensors are promising candidates for tracking applications in future high-energy physics experiments due to their excellent comprehensive performance in terms of radiation resistance, time resolution, position resolution and power dissipation. Driven by the requirements of Upstream Pixel Tracker in the LHCb Upgrade II and future electron-positron colliders, a...

After LHC Upgrade II at CERN, LHCb aims to run at an instantaneous luminosity of $1.5 \times 10^{34}/cm^2/s$ and a total integrated luminosity of $300 fb^{-1}$. To support this high-luminosity operation, upgrades are planned for the LHCb detectors, including the downstream tracker, known as the Mighty Tracker. One of the key upgrades is the introduction of silicon pixel detectors, called...

CMS Collaboration, Hsin-Yeh Wu (National Taiwan University)18/11/2025, 09:20Sensors for CalorimetryORAL
The CMS Collaboration is getting ready to replace its current endcap calorimeters with a high-granularity calorimeter (HGCAL) to overcome the high radiation effects and the unprecedented event pileup problems in the upcoming High Luminosity LHC (HL-LHC) era. HGCAL featuries a previously unrealized transverse and longitudinal segmentation, for both the electromagnetic and hadronic compartments,...

During the testing of pre-production and production of ATLAS ITk pixel modules the readout of modules can fail. These failures are due to issues in core columns causing the trigger processing inside the ITkPix chip to deadlock. This can be mitigated by disabling one or more core columns within the ITkPix chips. Disabling a core column results in a loss of 2% of the active area of a chip and...

ATLAS ITk Collaboration
We describe the extensive quality assurance programme undertaken during the production of the ATLAS ITk strip sensors. Quality Assurance (QA) is the systematic process of preventing defects during production, rather than identifying them after the fact. It uses well defined testing procedures to monitor the production process, ensuring consistent process control and...

To address the demanding operational requirements of the High-Luminosity upgrade of the Large Hadron Collider (HL-LHC), the ATLAS experiment is replacing its current Inner Detector with a new all-silicon Inner Tracker (ITk). The ITk will feature an active sensor area of 165 m², with its outer tracking layers populated by approximately 20,000 ATLAS18 n⁺-in-p silicon strip sensors manufactured...

The Alpha Magnetic Spectrometer(AMS-02) is a particle detector that operates on the International Space Station(ISS), which aims to search for antimatter, and dark matter while performing precision measurements of cosmic rays composition and flux. To enhance the detection acceptance by a factor of three, a new large-area silicon tracker layer (Layer-0) will be installed on top of AMS-02 in...

Mr J. Deng (School of Physics, Zhejiang University, Hangzhou, 310058, China)18/11/2025, 11:30Radiation Effects on DetectorsORAL
Radiation-hardened CMOS image sensors are critical for surveillance in nuclear facilities and other high-radiation environments. Under such application conditions, ionizing radiation may rapidly degrade the photodiode performance and significantly compromise the sensor’s imaging capability. In this study, radiation damage effects on photodiodes are reviewed, and several radiation-tolerant...

The Belle II experiment is currently recording data from $e^+e^-$ collision at the SupperKEKB accelerator, which holds the world's highest luminosity of $5\times10^{34}~\mathrm{cm^{-2}s^{-1}}$ and will be upgraded to achieve a higher luminosity of $6\times10^{35}~\mathrm{cm^{-2}s^{-1}}$. An R&D program has been established to develop a new vertex detector (VTX) the one currently operating in...
