FERMI is the seeded Free Electron Laser (FEL) user facility at Elettra laboratory in Trieste, operating in the VUV to soft X-rays spectral range. In order to extend the FEL spectral range to shorter wavelengths, a feasibility study for increasing the Linac energy from 1.5 GeV to 1.8 GeV is actually ongoing. The design of new S-band accelerating structures, tailored for high gradient operation, low breakdown rates and low wakefield contribution, is presented. First test results of a short prototype built in collaboration with Paul Scherrer Institut (PSI) will also be reported.
