The four planar detector stations of the CBM-MVD will operate between 5 and 20 cm downstream of the target in the moderate vacuum of the target chamber, which is placed in the center of the CBM dipole magnet with a maximum 1 T. The harsh radiation environment of up to 7$\times$10$^{13}$ n$_{\text{eq}}$/cm$^2$ and 5 Mrad per CBM running year poses challenging constraints not only on the...

In the Phase-2 upgrade of CMS and ATLAS, the scope of CO2 detector cooling systems will expand greatly. The systems will be larger, colder, and will see an order-of-magnitude increase in cooling power. The DEMO CO2 cooling system is a full sized prototype of the cooling systems for Phase 2. We have been operating DEMO for most of 2022 and 2023. In this two-part talk, we first address DEMO...

During LHC Phase II, the CMS tracker will be updated to increase its performance given by the higher luminosity. One of the goals of this upgrade is to cover the maximum surface and to not leave gaps around the interaction point, to increase the global performance of the detector. In order to reach it, TBPX (Tracker Barrel Pixel) design is divided into two halves, staggered layer by layer, to...

The upgraded CMS Tracker, to be installed prior to the high luminosity phase of LHC operation (HL-LHC), will require novel approaches to overcome the challenges posed by the extreme radiation environment. In addition, the tracker must remain extremely lightweight and at the same time provide an efficient cooling system (evaporative CO2).

**The main ITk structures for the ATLAS High-Luminosity LHC Upgrade consist of concentric carbon fiber cylinders, reinforced by hat stiffeners and thick flanges. These structures were manufactured in the US, and then shipped to Europe for dressing and assembly. Although very stiff when assembled, the cylinders are susceptible to large deformations under the dynamic loads occurring during...

The warm nose heat exchanger are used to control the temperature in the ATLAS detector through CO2 liquid/2phase heat exchange without any heater in the unreachable areas of the detector. Due to the limited space, these heat exchangers are produced with 3D metal printing. A large campaign is done to study different cleaning solution in order to reduce/eliminate any powder residues.

28. Heat Extraction through Structural Components of the CMS Phase II Tracker Forward Pixel DetectorDr Souvik Das (Purdue University (US))02/06/2023, 09:00
The CMS Inner Tracker Forward Pixel detector will be rebuilt for the instantaneous luminosity of 5 x $10^{34} \mathrm{cm}^{-2} \mathrm{s}^{-1}$ and up to 200 pp collisions at the High Luminosity LHC. To limit particle occupancy to the per mille level and improve track resolution, we will increase the granularity of the sensors. This will result in power dissipation of approximately 60 kW. For...

Future colliders, such as the Future Circular Collider (FCC-hh/ee), muon collider (MC), or electron-Ion collider pose different demands on detector mechanics and thermal performance. A common design criteria is low support mass and optimal thermal performance to effectively cool active detectors. Depending on the physics goals the support mechanics should only have between ~0.1 to 1% X_0...

High thermal capacities and low values of density and viscosity are some of the main characteristics of supercritical fluids. These, in combination with the nature of a supercritical fluid - a single phase fluid - make them very interesting candidates for the thermal management of High Energy Physics detectors.

During the Phase III Upgrade the Large Hadron Collider (LHC) will experience radiation levels extent never achieved before. The current detector cooling system operating with CO2 and the associated mechanical supports must be upgraded as the current cooling temperature is not sufficient to prevent the phenomena of the thermal runaway of the sensors. Indeed, over the years the CO2 cooling...

For future experiments, the coverage of larger surfaces with silicon trackers faces challenges related to the large number of sensors to be positioned, cooled and interconnected. A modular cooling substrate design must be adopted to access industrialised series production. Replacement of faulty sensors during their integration represents an additional design requirement.
