1. 3 June 09P. Tropea1 Cooling system acceptance Define a common set of acceptance criteria for cooling system commissioning Write the testing procedures suitable to match the above mentioned criteriaDatabase Define a common database of components/techniques to be used on different systems, as a function of the fluids, the type of cooling system and the environmental conditions (radiation, magnetic field) WP4: cooling systems acceptance and materials, components and technique database Detector cooling project, 3 June 2009

2. 3 June 09P. Tropea2 Acceptance criteria Proposals Leak detection –Test different sniffers (Ar, He, Freon…) –Measures of pressure drops: build a common instrumented rack for precise Dp measurements, review applicability of existing procedures –Leak calibration: measure/calculate leak rates with different gas/liquids, different T, p conditions… Cleanliness –Techniques for clean work: list and validate –Cleaning process definition/ acceptance criteria –Filtering techniques for different fluids/requirements Performance –Portable heater? –Which parameters to check and how: minimum instrumentation for performance tests
