Thermal design of an ejector-supported cycle using krypton for cooling of particle detector accelerators / Contiero, Luca (CERN ; Norwegian U. Sci. Tech.) ; Banasiak, Krzysztof (Norwegian U. Sci. Tech. ; SINTEF, Oslo) ; Verlaat, Bart (CERN) ; Hafner, Armin (Norwegian U. Sci. Tech.) ; Försterling, Sven (Unlisted, DE) ; Allouche, Yosr (Norwegian U. Sci. Tech.)
According to the High-Luminosity plan (HL-LHC) the Large Hadron Collider will be upgraded to further extend physics discoveries (2033–2034). The increase of the luminosity is followed by an increase of the radiation damage on the silicon sensors used to detect those particles, which they must be preserved from the thermal runaway after which the sensors reach electrical breakdown.

Cold Krypton system for the Phase III Upgrade of the LHC / Contiero, Luca (Norwegian University of Science and Technology (NTNU) (NO)) ; Banasiak, Krzysztof (Norwegian University of Science and Technology (NTNU) (NO)) ; Hafner, Armin (Norwegian University of Science and Technology (NTNU) (NO)) ; Verlaat, Bart (CERN) ; Petagna, Paolo (CERN)
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. [...]

Hybrid cycle with Krypton for cooling of future silicon detectors in HEP / Contiero, Luca (Norwegian University of Science and Technology (NTNU) (NO)) ; Hafner, Armin (Norwegian University of Science and Technology (NTNU) (NO)) ; Banasiak, Krzysztof (Norwegian University of Science and Technology (NTNU) (NO)) ; Barroca, Pierre Andre (CERN) ; Allouche, Yosr (Norwegian University of Science and Technology (NTNU) (NO)) ; Verlaat, Bart (CERN) ; Petagna, Paolo (CERN)
The Large Hadron Collider (LHC) will soon deliver much more radiation after LS4. The level of radiation has already pushed the current CO2 cooling unit to its limit, represented by the triple point (≈ -56°C). [...]

A new cold cooling system using krypton for the future upgrade of the LHC after the long shutdown 4 (LS4) / 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 detectors for high-energy physics experiments will require operation at lower temperatures to cope with radiation damage to the sensors and the consequent increase of dark current, beyond the limit of the current CO2 evaporative cooling system. This, along with other requirements such as mass minimization and high radiation hardness, drives the need for new advanced cooling technology. [...]

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. [...]

A prototype with Xenon to simulate the future advance refrigeration unit for cooling of silicon detector trackers / Contiero, Luca (Norwegian University of Science and Technology (NTNU) (NO)) ; Hafner, Armin (Norwegian University of Science and Technology (NTNU) (NO)) ; Banasiak, Krzysztof (Norwegian University of Science and Technology (NTNU) (NO)) ; Verlaat, Bart (CERN) ; Petagna, Paolo (CERN) ; Allouche, Yosr (Norwegian University of Science and Technology (NTNU) (NO))
The Large Hadron Collider (LHC) will soon undergo the Phase III Upgrade, resulting in radiation levels never achieved before. Therefore, both the detector cooling system and mechanical supports for future particle trackers should also be upgraded, as the current refrigeration technology using CO₂ is insufficient to prevent the thermal runaway of silicon sensors due to the CO₂ triple point temperature (≈ -56°C).

Tech.) ; Blust, Stefanie (CERN) ; Hulek, Wojciech (CERN) ; Zwalinski, Lukasz (CERN) ; Teixeira, Daniella (CERN)
A new CO$_2$ refrigeration concept is evaluated to cool the ATLAS and CMS experiments installed close to 100 m underground, at the Large Hadron Collider (LHC) at CERN. The first prototype unit produced to validate the conceptual design and to assess safety and reliability of the system has been commissioned. [...]
