Roger Ruber (Uppsala University (SE)), Volker Ziemann (Uppsala University (SE))

Workshop on the RF system design and prototyping for the ESS proton linear accelerator. RF system design issues in the ESS NC and SC linac, including discussions on the the RF power generation and distribution, LLRF and prototype testing. The output of this meeting will include input towards the technical design report and possible impacts on planning.
