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. [...]

LET Calibration of Ion Microbeams and Their SEE Cross Section Characterization / Peracchi, Stefania (ANSTO, Menai) ; Drury, Ryan (ANSTO, Menai) ; Pastuovic, Zeljko (ANSTO, Menai) ; Williams, Jesse (Wollongong U.) ; Tran, Linh T (Wollongong U.) ; Guatelli, Susanna (Wollongong U.) ; Pan, Vladimir (Wollongong U.) ; Archer, Jay W (Wollongong U.) ; Rosenfeld, Anatoly B (Wollongong U.) ; Coronetti, Andrea (CERN) et al.
The Australian Nuclear Science and Technology Organisation hosts the Center for Accelerator Science, a sovereign facility with light and heavy ion beams. The 10-MV ANTARES accelerator is equipped with one of the few heavy ion nuclear microprobes in the world, which has been upgraded with the unique external beam irradiation facility (EBIF). [...]

Measurement of the mass-changing, charge-changing and production cross sections of $^{11}$C, $^{11}$B and $^{10}$B nuclei in $^{12}{\rm C}+p$ interactions at 13.5 GeV/$c$ per nucleon. / NA61/SHINE Collaboration
We report results from a 2018 pilot run to study the feasibility of nuclear fragmentation measurements with the NA61/SHINE experiment at the CERN SPS. These results are important for the interpretation of the production of light secondary cosmic-ray nuclei (Li, Be, and B) in the Galaxy. [...]
