    In the context of the ALICE ITS3 collaboration, a set of MAPS small-scale test structures were developed in the 65 nm TPSCo CMOS process with the validation of the process for future vertexing applications as its primary focus.
    One such sensor, the Circuit Exploratoire 65nm (CE-65), and its evolution the CE-65v2, were developed to explore charge collection properties for varying...

  36. 8. Curved Mimosis as a preparation for FCC-SEED : status and plan.
    Jeremy Andrea

    The FCC-SEED is a new vertex detector concept that relies on high-granularity MAPS sensors, featuring low power consumption and a lightweight geometry. To achieve optimal performance with the smallest possible inner radius and minimal material budget, the FCC-SEED geometry is based on curved sensors.

    As preparatory work to develop expertise in bending, connecting, and testing curved...

  37. 2. Experimental verification of the Vertex detector Air Cooling system
    Andrea Moggi (Istituto Nazionale di Fisica Nucleare), Gherardo Ammirabile (Istituto Nazionale di Fisica Nucleare)

    We have developed a wind tunnel setup to experimentally study the cooling performance of a air flow cooling system for the inner vertex detector for FCC-ee. The staves of the vertex detector have been realised using a carbon fibre mechanical model with the same dimensions of the designed ones. The heat dissipation of the sensors is mimicked using kapton heaters. The setup can simulate about...

  44. 11. OCTOPUS: a R&D program towards a vertex detector for the future e+e- collider
    Dr Serhiy Senyukov (Institut Pluridisciplinaire Hubert Curien)

    The OCTOPUS project is a part of the CMOS working group of the solid state Detector Research and Development (DRD3). It involves 13 European institutes motivated by the R&D of fine-pitch pixel sensors, implemented in the TPSCo65 process to target key requirements of a vertex detector at a future lepton collider:

    1. sensors thickness down to 50 micron;
    2. fine pitch offering 3 um spatial...

  45. 14. R&D on flexible and low mass packaging for high-frequency communication of future MAPS detectors
    Dr David Novel (Fondazione Bruno Kessler)

    Minimizing the detector material budget to ≲ 0.3% of a radiation length X0 is one of the key challenges in building future experiments such as FCC-ee. A major obstacle to achieving this goal often lies not in the sensor itself, but in the FPC and the associated mechanical supports.
    Another critical requirement for future experiments is the transmission of high data rates, driven by the...

    Prof. Grzegorz Deptuch (Brookhaven National Laboratory)

    Monolithic Active Pixel Sensors (MAPS) have become central to modern vertexing and tracking detectors, but forthcoming facilities such as the FCC-ee will demand unprecedented power efficiency, timing precision, and bandwidth.
