Mr Dominic Howgill (University of London (GB)), Julien BONIS6/2/26, 8:30 AM
The Belle II detector at the SuperKEKB collider at KEK in Japan is the world’s intensity frontier flavour physics experiment at an e+e- collider. This experiment is collecting data at the forefront of accelerator and instrumentation capabilities. It is expected that the detector will need to be upgraded to handle increased data rates, and a silicon detector upgrade is proposed, which would...

Ms Margherita Rovini (INFN Pisa), Maurizio Massa (Universita & INFN Pisa (IT))6/2/26, 8:50 AM
In 2032 the SuperKEKB collider will undergo a major upgrade of the interaction region to reach the target luminosity of 6 × 10^35 cm⁻²s⁻¹. A new vertex detector (VTX) for the Belle II experiment will be required to match the new geometry of the machine components and will be based on Monolithic Active Pixel Sensors (MAPS) to provide improved robustness against the higher expected machine...

The LHCb Vertex Locator (VELO) is the silicon tracking detector located closest to the interaction region of the LHCb experiment at CERN’s Large Hadron Collider. A further upgrade is foreseen around 2034 to be able to operate at extremely high collision rates, which require new mechanical solutions to minimize material, improve thermal management, and ensure stable detector positioning close...

Yutaro Takahashi (Nikhef National institute for subatomic physics (NL))6/2/26, 9:30 AM
The upgrade of the LHCb Vertex Locator (VELO), planned to be installed in 2033, presents a wide range of mechanical engineering challenges driven by the need for minimal material budget, high radiation tolerance, and mechanical stability under stringent operating conditions.

Mr Xuhao Yuan (Institute of High Energy Physics, Beijing, China)6/2/26, 9:50 AM
The Alpha Magnetic Spectrometer-02 (AMS-02) experiment is currently the only magnetic spectrometer operating in space. It holds irreplaceable significance for addressing major scientific questions such as the existence of antimatter and the nature of dark matter. Based on its highly productive physics results and potential, the AMS is expected to operate until 2030 and undergo a detector...

Abstract— The ATLAS ITk Global Mechanics, which houses the silicon detector and provides a platform for detector integration is 2.2 meters in diameter and 6 meters long. The Strip Barrels are four 2.8 meter long support structures for the Strip Detector barrel staves. These cylinders are all eccentrically stiffened structures built from ultra-high modulus carbon fiber with cyanate ester...

As part of the ATLAS Phase II Upgrade, a new all-silicon tracker will replace the current Inner Detector to meet the demands of the High Luminosity Large Hadron Collider (HL-LHC). The future Inner Tracker (ITk) will include a five-layer pixel detector with extended rapidity coverage. In the central section of the three outer layers, the so-called Pixel Outer Barrel (OB) will adopt a layout...

Over the past 5 years, new joining procedures have been developed by CERN MME group in the framework of detector upgrades for ATLAS and CMS, to be installed during the LHC third Long Shutdown (LS3). These improved detectors rely on high-pressure CO2 cooling circuits reaching their innermost parts. This means that metallic piping is required to withstand pressures of up to 160 bar and...

Abstract
Go to contribution page
CMS Phase-II tracker and calorimeter subassemblies are currently in production, including their complex, high-pressure CO$_2$ cooling circuits. It is mandatory to ensure that these circuits are leak-tight and safe for operation. Adhering to CERN HSE’s regulations, any pipe assembly of the CO$_2$ cooling system must undergo specific tests and certifications. Furthermore, the... -

There is great interest in the High Energy Physics (HEP) community to replace the plastic and metallic pipes currently used in local supports/cold plates. The Vaporization of Sacrificial Components (VaSC) [1-2] enables the possibility to embed a network of channels directly into a composite laminate. After a poly(lactid acid) (PLA) preform with the desired network design is introduced within...
