4. Performance Targets for Multi-Functional Structures in Future Tracking Detectors

Giorgio Vallone (Lawrence Berkeley National Lab. (US))

04/06/2026, 08:40

Future collider particle detectors are being conceptualized worldwide. Most of these concepts foresee tracking systems significantly targeting per-layer material budgets at the 0.25–0.5% X₀ level, and simultaneously sustaining higher data rates, increased radiation doses, and stringent requirements on mechanical stability and cooling. In this regime, structural supports, services, and sensing...

26. Ultra-light mechanics for a large-area silicon tracker at FCC-ee

Giada Bonini (Universita e INFN, Perugia (IT))

04/06/2026, 09:00

The FCC-ee detector concepts feature tracking systems with a much larger volume than those of the LHC experiments, with dimensions of about 4 m in diameter and 4 m in length.
To meet the demanding physics performance requirements of FCC-ee, a silicon tracker must have an extremely low material budget, far beyond what has been achieved by large silicon trackers built to date.

This...

25. Prototyping and qualification of ultra-light ladders for the CMS TBPX L1 upgrade in preparation for a future replacement

Pier Filippo Cianchetta (Universita e INFN, Perugia (IT))

04/06/2026, 09:20

At the beginning of 2025, a collaboration at CERN started the development of an upgraded mechanical design for the CMS Inner Tracker TBPX L1 in preparation for its future replacement.
Building on concepts originally developed for the ALICE Inner Tracker, a new ladder design was developed to significantly reduce the material budget, achieving a reduction of about a factor of three at the...

72. Innovative mechanical structures via Additive Manifacturing

Giorgio Chiarelli (INFN Sezione di Pisa,)

04/06/2026, 09:40

dditive manufacturing (i.e.”3D printing”) is increasingly being used in a number of areas from aerospace to medicine. Recent advancements in technology are widening the applications in which the 3D printing includes carbon fibers, reinforcing the mechanical properties of the matrix. Continuous Fiber Reinforced Composites (CFRC) exhibits mechanical performances better than when short CF are...

52. Development of a material knowledge base for High Energy Physics Experiments

Nicola Pacifico (CERN)

04/06/2026, 10:40

High Energy Physics experiments make use of advanced materials that are often used within harsh environments, having to withstand radiation levels in the order of several MGy. Several data collections and databases have been compiled in the past, with the intent to provide the community with an entry point to material test data. We will report here on the efforts within the project 2 of Work...

69. Active vibration control of detector structures

Finn Barber (University of Oxford)

04/06/2026, 11:00

Active vibration control has potential to reduce error contributed by detector vibrations without adding significant mass to support structures.

Prototype outer-barrel staves for ePIC were used as a test-bed for an active vibration control system based on the well-known Filtered-X LMS algorithm, implemented on an FPGA. Erroneous stave oscillations, caused by the air cooling system, were...

9. Mechanical Performance of Carbon Fibre Composites After Proton Irradiation: Tensile Testing of Unidirectional and Woven Laminates

Todd Slater (University of Oxford (GB))

04/06/2026, 11:20

Carbon fibre is a popular choice for high performance, demanding applications. It has exceptional and customisable stiffness to weight ratios, strength to weight ratios, thermal stability, and design flexibility. However, future detector upgrades will expose these materials to increasingly high levels of radiation, therefore requiring a better understanding of radiation induced changes in...

27. Measuring Electrical Resistivity of the CMS TFPX Carbon Fiber Support Structures

Christine Angela McLean (The State University of New York SUNY (US))

04/06/2026, 11:40

This talk will cover recent efforts to measure the electrical resistivity of the carbon fiber composite support structures of the CMS Phase-2 Tracker Forward Pixels (TFPX). The efforts comprise a custom system built at Florida Tech as well as the use of a Quantum Design Physical Property Measurement System at the University at Buffalo. In the near term, the results will help to inform the TFPX...

65. Low Mass Carbon Composites with Integrated Thermal Pathways

Sushrut Rajendra Karmarkar (Purdue University (US))

04/06/2026, 12:00

Thermal management of particle sensors and electronics on carbon composite support structures is a critical challenge in particle detectors. This work presents a composite laminate design incorporating graphene/graphite sheets and carbon nanotube yarn to enhance thermal transport while maintaining structural performance. Integration strategies, including surface treatment and co-curing...
