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. Although studies on using noble gases for refrigeration purposes outside of deep cryogenic applications are extremely rare, the thermodynamic and transport properties of Krypton suggest great potential as a coolant in detector applications. Since silicon detectors are characterized by ultra-light and fragile structures requiring controlled cooldowns to avoid thermal shocks, a new cooling system was developed. This work presents the concept and strategies to be implemented to meet the harsh requirements imposed by detector cooling.
