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...
This talk will provide an overview of the beam-induced backgrounds at FCC-ee and the workflow established to study their impact on the detectors. The main background processes will be reviewed, together with the corresponding mitigation strategies. The current status of the studies on their impact on the detector performance will also be presented.
The design of the FCC-ee detector beam pipe will be presented, together with the ongoing R&D activities carried out at INFN Frascati. Particular emphasis will be given to the thermal performance studies and cooling measurements of the beam pipe prototypes. The limitations of the current design will be discussed, as well as possible optimisations and plans for future improvements.
The baseline vertex detector as described in the Feasibility Study Report of FCC-ee will be presented, together with the integration with the beam pipe and support tube.
We will discuss a study of the cooling services for the inner vertex using air-based system, as well as the one for the middle and outer barrel, and disks. Particular emphasis will be given to the integration aspects and...
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:
- sensors thickness down to 50 micron;
- fine pitch offering 3 um spatial...
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...
Give an overview of the Technology and ARCADIA submissions
The ARCADIA INFN collaboration developed a Fully Depleted Monolithic Active Pixel Sensor as a technology demonstrator, using the LFoundry 110nm CIS technology.
The whole high-resistivity substrate can be depleted, thanks to a custom backside process that allows a uniform electric field distribution inside the sensing volume. Several technology demonstrators have been developed with an...
Since 2019, the Belle II experiment at the SuperKEKB B-factory in Tsukuba, Japan has been collecting data from asymmetric-energy e−e+ collisions at the Υ(4S) resonance, holding the world luminosity record of 5.1×10^34 cm^-2 s^−1, reached in 2024.
The Vertex Detector (VXD) provides a vertex resolution of approximately 10 µm, allowing highly precise tracking and vertex reconstruction, essential...
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. At Brookhaven National Laboratory we are advancing several complementary innovations that collectively define the next generation of MAPS.
At the front end, we have...
