AGORA is a detector concept developed from studies for the Circular Electron Positron Collider (CEPC), with extensions towards FCC-ee and other future colliders. It aims to support precision electroweak measurements, Higgs and flavour physics, and searches for new physics. In particular, the large samples of bottom- and charm-flavoured hadrons and τ leptons produced during Z-pole operation...
Future collider detectors will require tracking detectors with a detection surface of several hundreds of square meters, combined with requirements on spatial resolution of a few microns per track, coupled with as small power consumption as possible. Specialized sensors with a time resolution of 100 ps or better will also be required to add TOF capabilities to the detectors. MAPS sensors are...
The development of monolithic silicon sensors with simultaneous high spatial and temporal resolution is being pursued at INFN within the ARCADIA project, with particular interest in applications requiring 4D tracking. The integration of internal gain in fully depleted CMOS sensors has led to the development of CMOS-LGAD devices, combining the fast signal formation of LGADs with monolithic...
The inner tracker (ITK) of the reference detector for Circular Electron Positron Collider (CEPC) imposes stringent requirements on mechanical support structures, including an ultra-low material budget, high stiffness, and long-term stability under radiation. This paper presents the full development of a 1000 mm long triangular-section carbon fiber reinforced polymer (CFRP) truss beam for the...
The Circular Electron–Positron Collider (CEPC) is designed to reach a center-of-mass energy of up to 360 GeV for electron–positron collisions, with the primary goals of precision studies of the Higgs boson and searches for physics beyond the Standard Model. The CEPC outer silicon tracker will cover a total active area of ~85 m² and employ advanced long microstrip AC-Coupled Low-Gain Avalanche...
The Circular Electron Positron Collider (CEPC) is a next-generation electron positron collider for precision studies of Higgs, flavor physics and beyond. The silicon Inner Tracker (ITk) is a key component of the whole tracking system. COFFEE/ChiR MAPS(monolithic active pixel sensor) chips fabricated with 55nm HV-CMOS process is aimed for the CEPC ITk requirements, like a few-micrometer spatial...
LHCb plans an Upgrade II detector for 2035 to operate at luminosities of 1.0× 1034cm−2s−1, accumulating over 300 fb−1. This will result in about 30 interactions per crossing, producing approximately 1500 charged particles within acceptance.
The higher luminosity requires an enhanced VErtex LOcator (VELO) to handle increased occupancies and radiation. New techniques will assign b hadrons to...
The Circular Electron Positron Collider (CEPC) aims to test the Standard Model and search for new physics through precision measurements of electroweak, Higgs, and heavy-flavour processes. CEPC plans high-luminosity operation at energies relevant to Higgs, W, and Z boson production, with an expected physics event rate of the order of 100 kHz at the Z pole. Under these conditions, beam-induced...
AC-coupled Low-Gain Avalanche Detectors (AC-LGADs) are leading candidates for 4D tracking systems at future high-energy physics colliders, such as the CEPC and FCC. These sensors target a simultaneous spatial resolution of ~10um and a timing resolution of <50 ps. This contribution reports on recent R&D progress spanning AC-LGAD sensor optimization, dedicated readout ASIC development, and...
Future high-energy physics facilities (HL-LHC, CEPC, FCC) and nuclear fusion experiments require detectors with superior radiation tolerance and high time resolution. Silicon carbide (SiC) has emerged as an ideal candidate to replace conventional silicon-based detectors, owing to its wide bandgap, high displacement threshold energy, high thermal conductivity, high critical breakdown electric...
The IDEA detector concept has been proposed for experiments future high-energy electron-positron colliders, covering a rich physics program from the Z to WW, H and ttbar. The tracking system of the IDEA detector concept consists of different subsystems: a vertex detector, with an inner and outer section, a drift chamber and a silicon wrapper between the drift chamber and the calorimeters. In...
The VErtex LOcator (VELO) detector is positioned around the beam interaction region of the Large Hadron Collider, as part of the LHCb experiment. It is fundamental to reconstruct primary vertices

OCTOPUS and MANTA are DRD3 projects developing Monolithic CMOS pixel sensors suitable for full-silicon tracking at future e⁺e⁻ colliders. A key target of OCTOPUS is a spatial resolution of 3 μm for vertexing, while MANTA is a generic, configurable pixel sensor designed for a wide range of tracking applications. MANTA targets a slightly relaxed spatial resolution of below 10 μm and investigates...
