Description

ESS is installing and testing the RF distribution systems including waveguide and coaxial components, circulators, RF loads for up to 155 high power RF systems; > 5000 RFDS components. This talk will present the early quality issues, waveguide tuning and how they were resolved. RFDS components are often considered trivial however, the initial high power operation revealed a number of serious issues with many components. We introduce some of the main issues and summarise the design changes carried out by us and our partners.
