Abstract: Abstract: IPN Orsay is strongly involved within the EURISOL and EUROTRANS projects, especially collaborating to the overall design of their linac architecture. Since a few years, main part of the R&D work is dedicated to the development of superconducting spoke cavities and their associated components (RF coupler, tuning system horizontal cryomodule, etc.). Following the very promising results obtained with our first single-spoke prototype (2-gap, 352MHz, beta 0.35), a new prototype has been designed and fabricated (2-gap, 352MHz, beta 0.15) in order to be integrated in a future linac. The mechanical and RF tests, done on this prototype, are presented. Then, an overview of the latest beam dynamics calculations performed to design a linac using spoke cavities will be described.
