In such a way, the vacuum compatibility is assessed before installation in the UHV system of the LHC. According to the equipment’s nature, the vacuum acceptance tests consist in functional checks, leak tests, outgassing rate measurements, evaluation of contaminants by Residual Gas Analysis (RGA), pumping speed measurements, and qualification of the sticking probability of Non-Evaporable-Getter coating. In this paper, the methods used for the tests and the acceptance criteria are described. A summary of the measured vacuum characteristics for the tested components is also given.
