To sustain the five-fold increase in instantaneous luminosity of the High-Luminosity phase of the LHC, the ATLAS experiment will replace its current Inner Detector with a new all-silicon tracker detector. The Inner Tracker (ITk) will consist of an inner silicon pixel detector, surrounded by layers of silicon microstrip sensors. The production phase of the ITk is starting during the year 2023....
The MALTA silicon pixel detector combines a depleted monolithic active pixel sensor
(DMAPS) with a fully asynchronous front-end and readout. It features a high
granularity pixel matrix with a 36.4 μm symmetric pixel pitch, low power consumption of <1 μW/pixel and low material budget with detector thicknesses as little as 50 μm. It achieves a radiation hardness to 100MRad TID and more than...
The High Luminosity LHC (HL-LHC) requires the CMS detector to undergo a major Phase-2 upgrade, which involves the complete replacement of current tracker. The new tracker will be divided into two main parts: inner tracker and outer tracker. The Phase-2 outer tracker will employ two types of silicon modules, 2S and PS, based on a novel pT discrimination concept. These modules aim to reduce...
The High Luminosity upgrade of Large Hadron Collider (HL-LHC) will increase the LHC Luminosity and with it the density of particles on the detector by an order of magnitude. For protecting the inner silicon detectors of the ATLAS experiment and for monitoring the delivered luminosity, a radiation hard beam monitor has been developed. We developed a set of detectors based on polycrystalline...
The current ATLAS Inner Detector will undergo a complete upgrade in order to meet the requirements of the High Luminosity Large Hadron Collider (HL-LHC). The new Inner Tracker (ITk) will be made completely of silicon sensors fabricated by Hamamatsu Photonics K.K. (HPK). Quality Assurance (QA) is focused on providing confidence that quality requirements will be fulfilled in production such as...
The new Inner Tracker of the ATLAS experiment will be installed during LHC Long Shutdown 3 and will consist of a pixel and strip detector. The Outer Barrel, comprising three central outer pixel layers, will be constructed using a combination of flat sections called longerons and inclined half-rings. Silicon modules will be mounted on these structures with good thermal contact and powered in...
Ultra-fast silicon detectors (UFSD) are a specialized type of radiation detectors based on Low Gain Avalanche Detectors (LGADs) that are designed to have extremely fast response times, typically in the range of picoseconds or even femtoseconds. The exceptional temporal resolution of UFSD enables the precise determination of the particle arrival time and helps disentangle overlapping collision...
In order to meet the physics goals of the forthcoming high luminosity (HL) era of the CERN Large Hadron Collider (LHC), the inner detector of the ATLAS experiment will be replaced by a new all-silicon tracking system, known as the inner tracker (ITk). The outer region of the ITk is instrumented with 22,000 n^+-in-p type silicon strip sensors manufactured by Hamamatsu Photonics...
Positron emission tomography (PET), is a profound imaging technique that exploits features of positron annihilation, where two back-to-back gamma photons emitted with 511 keV energies are detected in coincidence. In the current PET systems, only the photoelectric interaction of the gamma photons is considered, and their Compton scattering is assumed to have a parasitic effect. Since the...
Summary (Max 500 words)
ATLAS innermost detector layer will undergo a broad range of upgrades for the HL-LHC phase. To be able to cope with the new detector design and a large set of modules to be integrated on the ITk, a demonstrator-based project at SR1 facility in CERN is conducted, to test and integrate a large number of Pixel modules equipped with RD53a electronics.
To mimic the ITk...
After ten years of massive success, the Large Hadron Collider (LHC) at CERN is going for an upgrade to the next phase, the High Luminosity Large Hadron Collider (HL-LHC) which is planned to start its operation in 2029. This is expected to have a fine boost to its performance, with an instantaneous luminosity of 5.0×1034 cm-2 s -1 (ultimate value 7.5×1034 cm-2 s -1) with 200 average...
Monolithic CMOS Pixel Sensor (CPS) is one of the promising candidates for the Circular Electron Positron Collider (CEPC) Vertex detector, due to its good performance and trade-off of granularity, readout speed, material budgets and power consumption. A full-scale TaichuPix chip, including a matrix of 512 × 1024 pixels with a size of 25 × 25 μm2 is developed to provide a spatial resolution...
A new era of high rate pixel sensors has now arrived, across the imaging community there are a number of new devices utilising multigigabit serializers to tackle the requirements for greater frame rates and pixel counts. At STFC two such systems are currently under development with ICs delivered and camera systems under development alongside chip characterisation. Hexitec-MHz for photon...
