32. Status of the FCC-ee MDI full-scale mockup

Dr Andrea Moggi (Universita & INFN Pisa (IT)), Manuela Boscolo (INFN e Laboratori Nazionali di Frascati (IT))

6/3/26, 3:50 PM

The FCC-ee interaction region incorporates the crab-waist collision scheme to achieve unprecedented luminosity. This approach combines nano-beam focusing at the interaction point with a large horizontal crossing angle, which in turn requires a compact and sophisticated machine–detector interface layout.

To assess the feasibility of this advanced design, INFN and CERN have jointly launched...

29. Ultra-thin beam pipes for FCC-ee

Francesco Fransesini (INFN e Laboratori Nazionali di Frascati (IT))

6/3/26, 4:10 PM

The interaction region of the Future Circular Collider (FCC-ee) requires extremely thin vacuum chambers capable of withstanding thermal loads while minimising the material budget, thus requiring active cooling.
The chambers have been designed considering the baseline material AlBeMet162, selected to satisfy stringent requirements on stiffness‑to‑mass ratio while minimising material budget...

55. Structural Design and Thermal Performance Study of CEPC Beam Pipe Based on an Aluminum Tube Substitution Scheme

Xiaoyan Ma (Chinese Academy of Sciences (CN))

6/3/26, 4:30 PM

As one of the core components of CEPCr, the structural design and thermal management of the beam pipe directly impact beam quality and experimental safety. This study addresses the process validation requirements during the development of the beam pipe by proposing an experimental scheme that uses an aluminum pipe as a substitute for the conventional beryllium pipe. The beam pipe adopts a...

81. Large-Scale Curved Sensor Mechanics and Integration for Future Vertex Detectors

Bartlomiej Adam Markiel (CERN)

6/3/26, 4:50 PM

Next-generation vertex detectors for experiments such as ALICE ITS3, FCC-ee, and EIC demand a novel mechanical approach to achieve unprecedented tracking precision. This requires a radical reduction in material budget and positioning the first detection layer closer to the interaction point. Within the DRD8 collaboration (WP1), we have developed an ultra-light, wafer-scale curved silicon pixel...

11. Experimental studies for an air cooling system for the FCC-ee inner vertex

Gherardo Ammirabile (Universita & INFN Pisa (IT))

6/3/26, 5:10 PM

The inner vertex detector of the IDEA detector concept is based on MAPS technology, and is expected to dissipate less than about 50 mW/cm2. With such low power density air-cooling solutions can be developed. Two main mechanical arrangements for the silicon sensors are envisaged at the moment: a ‘traditional’ flat version, in which MAPS are put on top of a carbon fibre stave, and a curved...

43. Mechanical and Integration aspects of the FCC-SEED vertex detector concept

Jeremy Andrea (Centre National de la Recherche Scientifique (FR))

6/3/26, 5:50 PM

FCC-SEED is an innovative vertex detector concept designed for next-generation electron-positron colliders, particularly the Future Circular Collider (FCC-ee). The design leverages ultra-thin MAPS sensors, precisely bent to small radii to position the innermost layer in close proximity to the interaction point while conforming to the beam pipe. This approach minimizes material budget and...

10. Overview of the Mighty Tracker Challenges: Material Budget, Tight Envelopes, Installation

Ksenia Solovieva (University of Freiburg (DE))

6/3/26, 6:10 PM

In preparation for the High-Luminosity LHC planned for Run 5, the LHCb detector will undergo its second major upgrade (Upgrade 2). The five-fold increase in instantaneous luminosity will, in particular, pose challenges for the tracking system due to the increased occupancy and radiation conditions. The Mighty-Tracker upgrade aims to therefore replace the current Scintillating Fibre (SciFi)...

38. Lightweight hardware alignment system requirements and prototyping

Todor Georgiev Todorov (University of Freiburg (DE))

6/3/26, 6:30 PM

The ability to spatially align tracking detectors is imperative for fully exploiting their technological capabilities. A precise method to achieve this, proven by its use in many high energy physics experiments, is the use of tracks from particle decays and from cosmic rays traversing the detector [1-3]. However, the precision achievable with this method is dictated by the available data...

12. The LHCb Mighty Tracker: Thermo-mechanical design and prototype testing.

Mr Bilal Ganie (University of Manchester)

6/3/26, 6:50 PM

The LHCb experiment at the Large Hadron Collider will undergo a major
high-luminosity upgrade during Long Shutdown 4 as part of Upgrade II, tar-
geting instantaneous luminosities of up to 1.5 × 1034 cm−2 s−1, corresponding to
an order-of-magnitude increase over previous operation. This will increase the
total integrated luminosity from approximately 50 fb−1 to about 300 fb−1,...

62. New construction techniques for a fully carbon fiber DCH prototype

Alessandro Miccoli (INFN Lecce e Universita del Salento (IT)), Salvatore Maggiore (INFN Lecce e Universita del Salento (IT))

6/3/26, 7:10 PM

In the scenario of a future construction of an ultra-light drift chamber for the Future Circular Collider (FCC-ee), 4 meters long with an internal diameter of 80 cm and an external diameter of 400 cm, with a drift cell smaller than 1.5 cm, arranged in a full stereo configuration ( 50-250 mrad ) and instrumented with the Counting/Timing cluster technique, we propose the construction of a...
