Evaporative cooling with carbon dioxide for the detectors upgrade at the Large Hadron Collider.
Author(s) : ORIUNNO M., CEPEDA M., CONVERY M., et al.
Summary
Carbon dioxide is a very attractive refrigerant for scientific instruments where low mass and radiation hardness are required. In the context of the ATLAS Tracker upgrade for the Large Hadron Collider, the authors designed a local support structure with the cooling channel optimized for a two-phase flow of carbon dioxide. The prototype has been thermally characterized with a scalable and low-cost evaporative plant operated in open cycle (blow system). The temperature gradients are compared with measurements done with water at room temperature and with finite element models. A preliminary estimation of the heat transfer coefficients is provided.
