A test rig to study heat transfer of sCO2 at CERN / Pedano Medina, Camila Rocio (KIT - Karlsruhe Institute of Technology (DE)) ; Gleissle, Susanne (Offenburg University of Applied Sciences (DE)) ; Petagna, Paolo (CERN)
In high-energy physics (HEP) detectors and modern electronics, thermal management is critical to ensure reliable, long-term operation. Increasing power densities, compact geometries, and stricter environmental regulations are driving the need for efficient, low-GWP cooling solutions. [...]

Studies on supercritical carbon dioxide as a refrigerant for future detectors / Pedano Medina, Camila Rocio (KIT - Karlsruhe Institute of Technology (DE)) ; Petagna, Paolo (CERN) ; Mall-Gleissle, Susanne (Offenburg University of Applied Sciences) ; Wetzel, Thomas (Karlsruhe Institute of Technology)
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. [...]

Towards defining the optimal design parameters for a test setup studying heat transfer with carbon dioxide at supercritical conditions / Pedano Medina, Camila Rocio (KIT - Karlsruhe Institute of Technology (DE)) ; Petagna, Paolo (CERN) ; Mall-Gleissle, Susanne (Offenburg University of Applied Sciences)
As the demand for environmentally friendly refrigeration technologies continues to grow, the use of natural refrigerants for the thermal management of detectors for high-energy physics becomes increasingly relevant. While the use of boiling CO2 flows is well established at CERN for applications requiring cold conditions, this study focuses on investigating the heat transfer capabilities of carbon dioxide in supercritical conditions.

Applying krypton as refrigerant for cooling of future particle detector trackers at CERN / Contiero, Luca (Norwegian University of Science and Technology (NTNU) (NO)) ; Verlaat, Bart (CERN) ; Hafner, Armin (Norwegian University of Science and Technology (NTNU) (NO)) ; Banasiak, Krzysztof (Norwegian University of Science and Technology (NTNU) (NO)) ; Allouche, Yosr (Norwegian University of Science and Technology (NTNU) (NO)) ; Petagna, Paolo (CERN)
Future silicon-based particle detectors at CERN’s Large Hadron Collider will be exposed to higher radiation levels, requiring the silicon sensors to be kept at lower temperatures than those provided by the current cooling systems using CO2. Aiming to achieve temperature levels unattainable by CO2 and ranging between -60 to -80°C while maintaining environmental friendliness, the use of Krypton appears promising for the thermal management of future high-energy physics detectors.

An advance Krypton – CO2 cascade refrigeration unit for the Phase III Upgrade of the VELO detector at CERN / Contiero, Luca (Norwegian University of Science and Technology (NTNU) (NO)) ; Hafner, Armin (Norwegian University of Science and Technology (NTNU) (NO)) ; Verlaat, Bart (CERN) ; Banasiak, Krzysztof (Norwegian University of Science and Technology (NTNU) (NO)) ; Allouche, Yosr (Norwegian University of Science and Technology (NTNU) (NO))
The Vertex Locator (VELO) of the LHCb (Large Hadron Collider) experiment will soon undergo the Phase III upgrade to fully read out events in a higher irradiated environment. An unprecedented amount of radiation will lead to temperature levels unmanageable by the current CO2 cooling system (2PACL) developed at CERN-Nikhef. [...]

Krypton, applied as a refrigerant for cooling of silicon detector trackers / Contiero, Luca (CERN) ; Barroca, Pierre (Norwegian University of Science and Technology (NTNU) (NO)) ; Verlaat, Bart (CERN) ; Petagna, Paolo (CERN) ; Hafner, Armin (NTNU) ; Banasiak, Krzysztof (NTNU)
The thermal management of highly irradiated silicon detectors may soon require cooling temperatures beyond the limits of -45°C for the currently applied technologies with CO2. The working fluid shall be able to approach ultra-low temperatures for large heat loads using small piping and withstand a significant amount of radiation [...]

CO2 cooling challenges at CERN for the future phase 2 upgrade program / Verlaat, Bart (CERN) ; Petagna, Paolo (CERN) ; Zwalinski, Lukasz (CERN)
At CERN, evaporative CO2 is the baseline cooling solution for the thermal management of the phase 2 silicon detectors. Since 2008 CO2 cooling is used in 3 detectors with capacities ranging 1 to 15 kW at -30°C. [...]

Development and validation of a simulation tool for next generation detector cooling systems / Bhanot, Viren (CERN ; Manchester U.) ; Petagna, Paolo (CERN) ; Cioncolini, Andrea (Manchester U.) ; Iacovides, Hector (Manchester U.)
Carbon dioxide (CO$_2$) has emerged as a very suitable refrigerant for Tracker cooling applications in high-energy physics. It has been successfully implemented in a two-phase pumped-loop cycle on three experiments at CERN. [...]

New insights on boiling carbon dioxide flow in mini- and micro-channels for optimal silicon detector cooling / Hellenschmidt, D. (CERN, UBONN) ; Bomben, M. (CNRS-LPNHE) ; Calderini, G. (CNRS-LPNHE) ; Boscardin, M. (FBK) ; Crivellari, M. (FBK) ; Ronchin, S. (FBK) ; Petagna, P. (CERN)
Whilst the thermal management needs of future silicon detectors are increasing, the required mass and volume minimization of all detector ancillaries gets more demanding. This requires highly effective active cooling in very small channels. [...]
