The planned Atlas Upgrade silicon micro-strip detector system will employ an evaporative cooling system similar to the current system, but will utilize CO2 rather than fluorocarbon as the coolant gas in order to improve the heat transfer and coolant-to-wall heat transfer properties for small mass flows. This can be achieved due to the large latent heat capacity of CO2 relative to the existing fluorocarbon gas, however the utilization of this requires operating pressures far in excess of the current pressure system. As such, with operating pressures in excess of 150bara, it is essential to provide adequate testing of cooling systems to prevent catastrophic failure of the cooling elements. Safety and integrity testing of prototype and final design cooling loops will made possible by the equipment provided by this funding and will demonstrate our strategies to deal with both CO2 coolant leakage and highlight other potential failure sources.

计划中的Atlas升级硅微带探测器系统将采用与当前系统类似的蒸发冷却系统，但将使用CO2而不是碳氟化合物作为冷却剂气体，以改善小质量流的传热和冷却剂到壁的传热性能。由于CO2相对于现有的氟碳化合物气体具有大的潜热容量，因此可以实现这一点，然而，利用这一点需要远远超过当前压力系统的操作压力。因此，在工作压力超过150 bara的情况下，必须对冷却系统进行充分测试，以防止冷却元件发生灾难性故障。该资金提供的设备将使原型和最终设计冷却回路的安全性和完整性测试成为可能，并将展示我们处理二氧化碳冷却剂泄漏的策略，并强调其他潜在的故障来源。
