Advances in Pixel Detectors and Integration Technologies
The CMS silicon tracker will be replaced for the HL-LHC run of the experiment during LS3. The outer part of the new tracker is called Outer Tracker and consists of six barrel layers and endcap disks. Two types of modules have been designed, 2S modules (made up of two strip sensors) and PS modules (made of one strip, one macro-pixel sensor). The macro-pixel part of the PS module is called...
LHCb has recently submitted a physics case to upgrade the detector to be able to run at instantaneous luminosities of 2$\times 10^{34} cm^{-2}s^{-1}$, an order of magnitude above Upgrade I, and accumulate a sample of more than 300 fb$^{-1}$. At this intensity, the mean number of interactions per crossing would be 56, producing around 2500 charged particles within the LHCb acceptance. The...
The ALICE Inner Tracking System (ITS) has been recently upgraded to a full silicon detector consisting entirely of Monolithic Active Pixel Sensors (MAPS), arranged in seven concentric layers around the beam pipe. Further ahead, during the LHC Long Shutdown 3, ALICE intends to replace the three innermost layers of this new ITS with a novel vertex detector. To accomplish this, the proposed...
Monolithic active pixel sensors (MAPS) are now well established as a technology for tracking charged particles, especially when low material budget is desirable. For such applications, the design of the sensor focus mainly on optimizing the spatial resolution. Small pixels with coarse charge measurement and digital outputs are well suited for this purpose.
Within the European Union’s STRONG...
The Cooler-Storage-Ring External-target Experiment (CEE) which is being constructed since 2020 is a spectrometer to study the properties of nuclear matter at high baryon density region. An online beam monitor that is based on the time projection chamber detection principle is being developed for the CEE to accurately determinate the beam incidence position. The Topmetal-CEE sensors are used as...
Proton Computed Tomography (pCT) is an emerging imaging modality in particle therapy as it enables direct reconstruction of 3D map of relative stopping power (RSP) values of the target. A typical pCT detector records the direction and position of every single particle before and after crossing the target and residual energy after crossing the target. A typical pCT detector is thus made of...
The upgraded Inner Tracking System (ITS) of ALICE consists of 7 concentric layers of a custom monolithic active pixel sensor design known as ALPIDE. The ALPIDE-based detector design reduces the material budget to 0.35 $\%$ $X_0$ per layer for the innermost three layers (Inner Barrel), and to 1.0 $\%$ $X_0$ per layer for the outermost four layers (Outer Barrel), compared to 1.14 $\%$ $X_0$ per...
The tracking performance of the ATLAS detector relies critically on its 4-layer
Pixel Detector
The key status and performance metrics of the ATLAS Pixel Detector are
summarised, and the operational experience and requirements to ensure
optimum data quality and data taking efficiency will be described, with special emphasis to radiation damage experience.
By the end of the proton-proton...
High voltage CMOS pixel sensors have been proposed in several future particle physics experiments for particle tracking. ATLASPix3 is the first full reticle size (2×2 cm^2) Monolithic Active Pixel high voltage CMOS sensor, developed in context of the ATLAS upgrade for High Luminosity Large Hadron Collider (HL-LHC). It is designed to meet the specifications of outer layers of the ATLAS inner...
Low power consumption, high bandwidth and radiation tolerant VCSEL driving ASICs have been prevailingly researched and used in particle physics experiments. This paper presents the design and the test results of a 14-Gbps VCSEL driving ASIC fabricated in 55 nm CMOS technology.
The whole ASIC includes four independent channels, and each channel has the fixed channel height of 250 μm to keep...
