| Outline of Final Research Achievements |
We have developed a detector cooling system using 2-phase CO2 as the coolant aiming at applications to state-of-the-art detectors for nuclear and particle physics experiments. In the 2-phase CO2, gas phase and liquid phase CO2 co-exist, and the large latent heat of CO2 is used for cooling. We have conducted the R&D in order to solve the challenges such as degradation of O-rings, which could happen under environment of high pressure CO2, and instability of cooling temperature. By solving these issues, we have succeeded to construct a prototype of the cooling system which can cool detectors stably between -40°C and +15°C.

| Academic Significance and Societal Importance of the Research Achievements |
本研究によって開発された２相CO2冷却システムは先端的な素粒子・原子核実験に用いられる測定器の冷却に幅広く応用可能なものであり、これらの分野の実験的研究に貢献できる。他のR&Dグループで採用された方式に比べてコストを抑えられるため、応用範囲は広いと思われる。また、CO2はフロンに比べて地球温暖化係数がはるかに小さいため、測定器冷却以外にも、フロンを用いた冷却システムの代替品としての応用の可能性もある。
