This report will present the overall development of the High-Granularity Timing Detector (HGTD) for the ATLAS experiment at the Large Hadron Collider (LHC) by the China team.
ATLAS high granularity timing detector Module assembly and loading
The High Luminosity LHC (HL-LHC) phase, scheduled to start in 2030 and deliver 3000 fb-1 in 10 years, will offer unique potential for precision measurements and searches for rare processes. However, it will also pose significant challenges for the detectors due to extremely high radiation levels and the large number of simultaneous interactions per bunch crossing (up to 200). To mitigate...
The High Granularity Timing Detector (HGTD) will be installed in the ATLAS experiment as part of the Phase-II upgrade for the High Luminosity-Large Hadron Collider (HL-LHC). It will mitigate pile-up effects in the forward region, and measure per bunch luminosity. The design of HGTD is based on Low Gain Avalanche Detector (LGAD) sensors. This talk presents the results of beam-test campaigns...
The first part of this report will give a summary of the MTD BTL testbeam results at CERN during 9.10-9.24. The second part will be the low temperature test for the whole tray at TIF CERN.
The development of next-generation particle detectors capable of precise 4D tracking is crucial for future high-energy physics experiments. AC-LGAD have emerged as a leading technology to achieve excellent spatial and temporal resolution simultaneously. This report details the successful development and characterization of a new batch of AC-LGAD detectors fabricated by the University of...
As the Large Hadron Collider enters the High-Luminosity era, several sub-detectors require major upgrades. The ATLAS High Granularity Timing Detector (HGTD), currently under development for the HL-LHC, is designed to mitigate pile-up levels of up to ~200 simultaneous proton-proton interactions by providing precise timing information in the forward region (roughly 2.4 < |\eta| < 4.0). When...
The most important task in current particle physics is to precisely test the standard model of particle physics and search for new physics beyond the standard model. With the expansion of experimental exploration fields in new physics and increasing demands for exploration precision, detection technology and experimental methods are constantly facing new challenges. In order to fully utilize...
This report is about the progress of producing CMS HGCal module in IHEP. The CMS China group will undertake approximately one-fifth of the production tasks for silicon modules and most of the CuW baseplates.
The ALICE Forward Calorimeter (FoCal), to be installed during LS3 for Run 4, targets precision measurements of direct photons at forward rapidity and thus constrains gluon distributions in protons and nuclei. The expected performance of the electromagnetic section (FoCal-E) is assessed with SystemC models of ALPIDE-based pixel layers and SPS H2 beam data. In these studies, occupancy and...
The electromagnetic calorimeter (ECAL) is a key component of the LHCb experiment. To cope with the higher performance requirements imposed by the High-Luminosity LHC (HL-LHC) upgrade, the LHCb ECAL will be upgraded with the new PicoCal design. In the upgrade, novel spaghetti calorimeter (SpaCal) modules will replace the existing Shashlik modules in the central region of the ECAL. These modules...
The LHCb experiment at the Large Hadron Collider (LHC) will undergo a major upgrade of its electromagnetic calorimeter (ECAL) during Long Shutdown 4 (LS4). To optimize the ECAL design and enhance its physics performance, we evaluate the energy/time resolution through simulations of a single prototype based on different setups. Additionally, we evaluate the ECAL's response in different physics...
The LHCb experiment is preparing for its Upgrade II, during which the instantaneous luminosity will increase by at least a factor of five with respect to Run 3, reaching $1.0×10^{34}cm^{−2}s^{−1}$. The increase in luminosity is very demanding on the detectors. To address these challenges, the current silicon micro-strip Upstream Tracker (UT) will be replaced by a new Upstream Pixel (UP)...
At the future collider High-Luminosity LHC (HL-LHC), the average number of the simultaneous pp interactions per event, or pile-up (μ), will rise to as much as 200. Resolving the pile-ups using time measurement has already been investigated during LHC Phase-Il Upgrade, e.g. the ATLAS High Granularity Timing Detector (HGTD), which will be placed outside the ATLAS Phase-Il Inner Tracker (ITk)...
The report mainly introduces the development and testing of CuW baseplates used in the CMS experiment HGCal project, as well as the current progress of production and inspection acceptance of the IHEP designed CuW edition
During the third long shutdown of the LHC (LS3), the LHCb experiment will strengthen and upgrade the central area of the electromagnetic calorimeter (ECAL). In the most central area of the ECAL, a new sampling structure and new calorimeter modules will be used to address the performance degradation of the calorimeter in an extremely high radiation environment. The feature of this new sampling...
With the increasingly demanding requirements of high luminosity collider HL-LHC, High-Voltage CMOS (HV-CMOS) sensors, featured a deep n-well separating the transistors and the depletion region, had great radiation resistance and enhanced hit density processing capabilities, is considered as the technology option for LHCb upstream pixel tracker in LHCb Upgrade II. To reduce power density and...
The ATLAS experiment will replace its Inner Detector with an all‑silicon ITk for Phase‑2. To ensure production quality of ATLAS18 silicon strip sensors—designed to withstand up to 4000 fb−1—we establish a streamlined QA program built on standardized IV, CV , and CCE measurements at IHEP using a dedicated test piece (Mini sensor for CCE, MD8 for IV/CV). Irradiation tests are included as part...
The ALICE ITS3 is a novel vertex detector that will replace the innermost layers of ITS2 during Long Shutdown 3 (LS3). Composed of three fully cylindrical layers of wafer-sized 65 nm stitched Monolithic Active Pixel Sensors (MAPS), the ITS3 enables high-resolution tracking of charged particles generated in heavy-ion collisions. As stitched sensor prototypes produced in the ER1 phase of the...
This summary covers key aspects of UP detector assembly development, including an overview of the detector’s geometric structures, the dummy assembly process for UP detector modules, the design of subsequent automated fixtures, and an exploration of realizing automated assembly via robotic arms and gantries.
Beam test plays an essential role in validating the performance of silicon strip detectors for the ATLAS Inner Tracker (ITk) upgrade for the High-Luminosity LHC. This contribution presents recent beam test results for two ITk strip detector modules, highlighting both validation of analysis frameworks and insights into irradiation effects. As a cross-check of existing results and an exercise in...
The production of BIS RPC (Resistive Plate Chamber) singlets is a crucial aspect of the ATLAS Phase-II upgrade, designed to enhance the detector's performance for the High-Luminosity LHC (HL-LHC). BIS RPCs are engineered to meet the challenges posed by high radiation and pileup conditions in the HL-LHC environment. This work will focus on the production and assembly methods of BIS RPC...
Peking University actively participates in the CMS-GEM upgrade project for CMS muon system. This report will present the status and progress of CMS-GEM ME0 project, including the assembly and testing of the ME0 modules in Peking University in 2025, the acceptance test and the performance of the ME0 GEM electronics boards produced in China.
A dedicated data acquisition (DAQ) system based on a field-programmable gate array (FPGA) has been developed for the performance evaluation of Resistive Plate Chambers (RPCs) using cosmic rays. The system integrates 144-channel time-to-digital conversion with sub-100 ps precision, enabling accurate measurement of signal timing and charge information. A pipeline architecture with per-channel...
In order to cope with the higher flux delivered by the HL-LHC, 3 layers of RPC detectors will be installed in the Barrel Inner (BI) region of ATLAS during the phase-II upgrade. Benefiting from the thin-gap structure and sensitive front end electronics, the new generation RPC has higher rate capability and longevity, together with better time and spatial resolution. This talk will report the...
