76. Tracking and Vertexing at FCC-ee

Andrea De Vita (CERN & Università di Padova)

23/07/2026, 09:00

Oral

The first phase of the Future Circular Collider (FCC) program aims to deliver electron–positron collisions at unprecedented luminosities, enabling a precision physics program that places stringent requirements on detector performance and reconstruction algorithms.

This contribution presents the current status of tracking and vertexing developments for FCC detectors, with a focus on gaseous...

21. Vertex detectors at the FCC-ee – Requirements, layouts, and link to MAPS R&D

Armin Ilg (University of Zurich)

23/07/2026, 09:20

Oral

The electron–positron Future Circular Collider (FCC-ee) is the European particle physics community’s plan A for succeeding the LHC as the world’s premier collider facility. Precise reconstruction of primary and secondary interaction vertices is central to the FCC-ee physics programme, enabling measurements of rare flavour processes and of Higgs and Z boson decays to bottom, charm and strange...

38. Design and status of the ePIC Silicon Vertex Tracker detector for the Electron-Ion Collider

Laura Gonella (University of Trieste and INFN)

23/07/2026, 09:40

Oral

The Electron-Ion Collider (EIC) is a new accelerator facility under construction at the Brookhaven National Laboratory to investigate the internal structure and dynamics of strongly interacting matter. Starting in the mid-2030s, the EIC will collide polarized electrons with polarized protons and light ions, as well as with unpolarized heavy ions, across a wide range of center-of-mass energies,...

57. 4D Semiconductor Tracking Detector R&D for CEPC

JIA JIAN TEOH (中国科学院高能物理研究所(IHEP)), Jia Jian Teoh (Chinese Academy of Sciences (CN))

23/07/2026, 10:00

Oral

The Circular Electron–Positron Collider (CEPC), designed to operate at center-of-mass energies up to 360 GeV, aims to enable precision studies of the Higgs boson and searches for physics beyond the Standard Model. Its silicon tracker, with an active area of approximately 100 m², is designed to provide high-precision charged-particle tracking over a wide momentum range from below 1 GeV to above...

40. ARCADIA fully-depleted CMOS sensors for future vertex and silicon trackers

Matteo Barbagiovanni

23/07/2026, 10:50

Oral

The detection of charged particles and photons with high efficiency, excellent spatial resolution, and precise timing represents one of the most demanding challenges in the design of modern semiconductor detectors. Fully depleted CMOS monolithic sensors address these requirements by integrating sensor, readout, and signal processing electronics within a single silicon substrate while enhancing...

69. Performance Studies of the CASSIA Monolithic Sensors with Internal Amplification

Leena Diehl (University of Zurich (CH))

23/07/2026, 11:10

Oral

The CASSIA (CMOS Active SenSor with Internal Amplification) project is focused on developing monolithic active pixel sensors (MAPS) with internal signal gain in the Tower 180nm CMOS process.
An internal amplification enables the simplification of the in-pixel electronics while simultaneously improving the signal to noise ratio for radiation hardness and offering the potential for excellent...

50. Characterisation of pixel chip prototypes for ALICE 3

Elena Dall'Occo (CERN)

23/07/2026, 11:30

Oral

A major upgrade of the ALICE experiment is foreseen for Run 5 of the LHC. The new retractable Vertex Detector (VD) is a crucial component of the upgraded experiment and will achieve an unprecedented pointing resolution owing to its close proximity to the interaction point, with three layers installed inside the beam pipe, in combination with a low material budget. Monolithic active pixel...

11. Status of the OCTOPUS project

Dominik Dannheim (CERN)

23/07/2026, 11:50

Oral

The OCTOPUS project focuses on the simulation, development, and evaluation of fine-pitch monolithic pixel sensors produced in the 65 nm TPSCo process. All activities are pursued within the DRD3 collaboration on solid-state detectors. The key final development goals target the requirements of vertex detectors for future lepton-collider experiments. They include a single-point resolution of 3...

89. Monstera - status and latest developments of CMOS strips

Marta Baselga (Technische Universitaet Dortmund (DE))

23/07/2026, 12:10

Oral

Large tracking detector volumes for next generation particle physics experiments require scalable technologies at moderate costs and at highest possible integration levels to reduce system complexity. The Monstera project investigates fully integrated strips developed in LFoundry 150nm HV-VMOS, based on previous successful testing of passive strips. The design profits from the exiting readout...
