Abstract: The STCF is designed as one of the viable successor of the BEPC II, with 100 times higher luminosity promotion. The increased luminosity benefits the τ-Charm physical research, however asking for an advanced high-performance detector system. To get an optimal performance, a new MUC design with 3 layers of bakelite-RPC and 7 layers of scintillator detector is proposed. This design...
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...

n preparation for the coming years of LHC running at higher luminosity, two upgrade projects of the ATLAS Muon spectrometer have been developed: the New Small Wheel project, improving the trigger in the end-cap regions, and the BIS78 project, dedicated to the transition region between barrel and the endcaps (1<|eta|<1.3).
The BIS78 project will add 32 RPC triplets along z on the edges of...

The innermost end-cap muon station of the ATLAS detector is being upgraded with the New Small Wheel (NSW) using new technology for precision tracking and triggering: Micromegas (MM) and small-strip Thin Gas Chamber (sTGC). Each of the two NSWs will consist 8 large and 8 small sectors. A sector is a combination of the sTGC wedges on either side of a double Micromegas wedge. Four Micromegas...
LHCb has recently submitted a physics case to upgrade the detector to be able to run at instantaneous luminosities of 1.5$\times 10^{34} cm^{-2}s^{-1}$, 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 42, producing around 2000 charged particles within the LHCb acceptance. The...
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...
A possible solution to cope with the increased pile-up achieved at the HL-LHC and beyond is the 4D tracking, using time measurements in addition to space.
New sensor technologies are being explored to achieve the time resolution required for this new approach.
In this presentation we show the most recent results obtained with devices under test studied with tracks reconstructed by the...
ATLAS endcap inner station muon detector is being replaced with a New Small Wheel (NSW) detector to handle the increase in data rates and radiation expected at HL-LHC. The NSW will feature two new detector technologies, Resistive Micromegas (MM) and small-strip Thin Gap Chambers (sTGC). Both detector technologies will provide trigger and tracking primitives. The sTGC detector is composed of...
The High Luminosity upgrade of the LHC (HL-LHC) places unprecedented requirements for background monitoring and luminosity measurements. The CMS Tracker Endcap Pixel Detector (TEPX) will be adapted to provide high-precision online measurements of bunch-by-bunch luminosity and beam-induced background. The implementation of dedicated triggering and readout systems, the real-time clustering...
In HL-LHC operation the instantaneous luminosity will reach unprecedented values, resulting in about 200
proton-proton interactions in a typical bunch crossing. The current ATLAS Inner Detector will be replaced
by an all-silicon system, the Inner Tracker (ITk). The innermost part of ITk will consist of a state-of-the-art
pixel detector.
Several different silicon sensor technologies will be...
The NA61/SHINE experiment at the CERN SPS is undergoing a major upgrade during the LHC Long Shutdown 2 period (2019-2021). The upgrade is essential to fulfill the requirements of the new open charm and neutrino programs. In these programs the NA61/SHINE will operate with the data acquisition rate increased by a factor of 10, which requires an upgrade of current Beam Position Detectors (BPDs)....
The new ALICE Inner Tracking System is the first large-scale MAPS-based tracking system. It is covering an active surface of 10 m², with a total of 12.5 billion pixels. Several optimisations of the pixel chip lead to a quasi-noise-free operation, with measured fake-hit rates of below 1 hit per pixel and billion events (system level numbers), numbers compatible with the order of magnitude...

At the same time, the operation in the dual-phase...
The muon end-cap inner station of the ATLAS detector is being replaced by New Small Wheels (NSWs). The NSWs will effectively improve the online muon identification and maintain the current muon transverse momentum resolution despite the increased detector hit rates. The NSWs combine the Micromegas and small-strip Thin Gap Chambers(sTGC) technologies. The sTGC detector modules are arranged inw...
In the HL-LHC scenario, the CMS experiment will need to operate at up to 200 interactions per 25 ns beam crossing time and with up to 3000 fb$^{-1}$ of integrated luminosity. To achieve the physics goals the experiment needs to improve the tracking resolution and the ability to selectively trigger on specific physics events. The CMS Tracker upgrade requires designing a new detector to cope...
