2 CO2 Cooling Test Status 1.4mm ID, 5.5m length cooling pipe tested in different heat loads and flow conditions. Available empirical models for two phase pressure drop prediction were used and compared with experimental data. Upgrades on the test setup are being made in order to improve the measurements. Pixel cooling pipe mockup provided by PSI will be tested during the following weeks. 29 November 2018 João Noite PH-DT
