The focus of this work is the current CMS capillary production state in view of the upcoming upgrade. Capillaries play a key role in a cooling loop by ensuring proper flow distribution among parallel branches. For this purpose, it is important that they are sized such that a given flow rate through each capillary produces the desired pressure drop.
Due to their small dimensions large...

During the CMS Phase-2 upgrade, the cooling system of the CMS Tracker will be enhanced to operate its subsystems at temperatures down to -35degC. The cooling medium - liquid CO2 - will be distributed via Detector Transfer Lines (DTLs), passing through PP1s (Patch Panel 1) and then through the Tracker Service Channels (TSCs) before reaching the detectors inside the Tracker.

Seismic vibration and local disturbances of any origin represent a nodal problem of ground-based detectors for Gravitational Waves observations and studies. The INFN Pisa group has been involved for more than 25 years in this research field, and it has collected fundamental experience on the development of the Superattenuator (SA), the best mechanical system in the world conceived for...

The upgrade of the ATLAS Inner Tracker for the High-Luminosity LHC faced a critical challenge: thermal cycling from +20°C to -35°C induced cracks in silicon sensor modules due to coefficient of thermal expansion (CTE) mismatches between sensor materials and hybrid components. Finite element analyses revealed that the combination of stiff (TrueBlue) and soft (SE4445) adhesives exacerbated...

Abstract:
In view of LHCb Upgrade II, taking place during Long Shutdown 4, the detector is going to be modified to operate at a several times higher instantaneous luminosity compared to Upgrade I. The Mighty-Tracker, which replaces the present Scintillating Fibre...

The ATLAS and CMS Phase 2 upgrade presents multiple challenges, one of which is the need to test the 2PACL based CO2 detector cooling system’s performance of multiple units in a short time frame with a limited team.

To address this requirement, various solutions were explored in the development of 2PACL control systems, ultimately leading to the implementation of a feature called Autoscan.... -

The cooling capacity of the CMS Phase-2 pixel barrel mechanics must be significantly higher than that of the first two generations of CMS pixel detectors due to the increased granularity of the pixel readout chip and the corresponding higher power dissipation, as well as much higher expected total irradiation dose. All barrel ladders undergo thorough quality control tests with respect to...

The focus of this work consists of thermal quality control of the TB2S ladder structures for the future CMS tracker, currently in construction for use in the High-Luminosity Large Hadron Collider (HL-LHC). Efficient and reliable cooling is crucial to ensure proper functioning of the tracker in the HL-LHC conditions, throughout the detector lifetime.

Seismic attenuation is a crucial aspect for the mirrors used in Gravitational Wave (GW) interferometric experiments, as the RMS ground motion is many orders of magnitude higher than the signal to be detected. For this reason, technologies capable of efficiently attenuating vibrations in high mass systems have been extensively developed in this field.
