For the HL-LHC upgrade the current ATLAS Inner Detector is replaced by an all-silicon system. The Pixel Detector will consist of 5 barrel layers and a number of rings, resulting in about 14 m$^2$ of instrumented area. Due to the huge non-ionizing fluence (1e16 n$_{eq}$/cm$^2$) and ionizing dose (5 MGy), the two innermost layers, instrumented with 3D pixel sensors (L0) and 100µm thin planar...
The Phase-2 Upgrade of the CMS experiment is designed to prepare its detectors for operation at the High Luminosity Large Hadron Collider (HL-LHC). The upgraded collider will begin operation in 2026, featuring new challenging conditions in terms of data throughput, pile-up and radiation, reasons for which the tracker detector will be entirely replaced by a new design. We present the current...
ATLAS is preparing for the HL-LHC upgrade, where integrated and instantaneous luminosity will reach unprecedented values. For this, an all-silicon Inner Tracker (ITk) is under development with a pixel detector surrounded by a strip detector. The strip system consists of 4 barrel layers and 6 EC disks. After completion of FDRs in key areas, such as Sensors, Modules, Front-End electronics and...
The ATLAS tracking system will be replaced by an all-silicon detector for the HL-LHC upgrade around 2025. The innermost five layers of the detector system will be pixel detector layers which will be most challenging in terms of radiation hardness, data rate and readout speed. A serial power scheme will be used for the pixel layers to reduce the radiation length and power consumption in cables....
The Phase-II upgrade of the LHC will result in an increase of the instantaneous luminosity up to about 5×1034 cm−2s−1. To cope with the challenges the current Inner Detector will be replaced by an all-silicon Inner Tracker (ITk) system. The Pixel Detector will have to deal with occupancies of about 300 hits/FE/s as well as a fluence of $2×10^{16}$n$_{eq}$cm$^{−2}$. 3D Pixel sensors will be...
ALICE is planning to replace its innermost tracking layers during LHC Long Shutdown 3 with a novel detector that will be as close as 18 mm to the interaction point and as thin as <0.05% X0 per layer. To achieve these figures, a wafer-scale Monolithic Active Pixel Sensor in 65 nm technology is being developed. This sensor, fabricated on 300 mm wafers, will reach dimensions of up to 280 by 94...
The High Luminosity phase of the LHC (HL-LHC) will result in an increase of beam
energy, a higher collision rate, and a harsher radiation environment. A challenge for CMS is to maintain an efficient and reliable trigger for muons with eta > 1.6. Gas Electron Multiplier (GEM) technology can operate well at high particle fluxes and will be employed in the upgrade of the endcap muon system. The...
The inner 2 layers of the Belle II VXD are based on DEPFETs (PXD). This technology allows the construction of the currently most light-weight pixel detector in operation (0.2% X$_0$ in the acceptance area). It is the first time that this technology is deployed at a HEP experiment. PXD is in operation in Belle II since 03/2019 and is taking data with very good performance. The S/N is close to...
The T2K collaboration is preparing a rise of the beam intensity to increase the exposure aimed at establishing leptonic CP violation at 3 $\sigma$ level for a significant fraction of the possible $\delta_{CP}$ values. The near detector ND280 upgrade could reduce the overall statistical and systematic uncertainties at the appropriate level of better than 4%.
We have developed an innovative...
ALICE is the CERN LHC experiment optimised for the study of the strongly interacting matter produced in heavy-ion collisions and devoted to the characterisation of the Quark-Gluon Plasma. To achieve the physics program for LHC Run 3, a major upgrade of the experimental apparatus is ongoing. A key element of the upgrade is the substitution of the Inner Tracking System (ITS) with a completely...
At Jefferson Lab, the new CLAS12 spectrometer has been collected its first physics data with a 10.6GeV electron beam at a luminosity of $10^{35}$cm$^{-2}$s$^{-1}$. The Central Vertex Tracker (CVT) is situated within a 5T-solenoidal field surrounding a proton target. It consists of a tracker based on Micromegas and silicon detectors used in combination, in order to optimize spatial resolution...
The ATLAS collaboration at LHC has chosen the resistive Micromegas (MM) technology, along with the small-strip Thin Gap Chambers (sTGC), for the HL upgrade of the first muon station in the high-rapidity region, the so called New Small Wheel (NSW). Installation of the first NSW is foreseen in 2020. The construction of the four types of large size quadruplets, with surface areas between 2 and 3...
The sPHENIX detector at RHIC is being designed to precisely measure jets, jet correlations, and dilepton pairs with the goal of learning about the energy-dense quark-gluon plasma. With these measurements in mind, sPHENIX will employ a compact TPC covering 20cm < r < 78 cm and |𝜂| < 1.1 as the central tracker.
Utilizing an optimized Ne-CF4 gas mixture, zigzag readout pads, a 1.4T solenoid,...
BESIII (Beijing Spectrometer III) is a multipurpose spectrometer optimized for tau-charm physics. Detector and accelerator are upgrading to allow BESIII to run until 2029.
Cylindrical Gas Electron Multipliers will replace the inner drift chamber to improve both secondary vertex reconstruction and the radiation tolerance. The CGEM-IT will be composed of three concentric layers of cylindrical...
T2K is a long-baseline neutrino experiment based in Japan that aims to observe for the first time the violation of the CP symmetry in the neutrino sector. The upgrade of the magnetized near detector (ND280) is under development. The neutrino active target is a 3D highly segmented plastic scintillator detector (SuperFGD) made of about two million cubes. The light readout is based on sixty...
