FERMI@ELETTRA is a soft X-ray forth generation light source under development at the ELETTRA laboratory. It will be based on the existing 1.0 GeV Linac, revised and upgraded to fulfil the stringent requirements expected from the machine. The overall time schedule of the project is very tight and ambitious, foreseeing to supply 10 nm photons to users within 2010. Here the machine upgrading program and the ongoing activities are presented and discussed.

In the new Elettra full energy injector, bunch charge measurements will be performed by different types of current transformers (CT), depending on their position (single pass or multi pass sections). In the single pass sections (Linac and Transfer lines) a new type of current transformer (in-flange CT by Bergoz) will be used. Main advantage of this device is a compact and reliable design; they are also specially suited in space critical application. For the booster ring a standard DC current transformer will be used to measure the DC component of the circulating beam current. The housing has been developed in house, including the magnetic shield and the ceramic gap in the vacuum chamber. Furthermore, calculations of the trapped modes in the current monitor housing are described. Longitudinal coupling impedance and loss factors for these resonant modes are estimated and we showed that dissipated power is not critical with ELETTRA booster parameters.

Changes in the longitudinal impedance budget occur due to the changes in the machine structure. In this paper we update the longitudinal impedance budget of Elettra following the installation of the new vacuum chambers in the last three years. The measurements are performed by mapping the horizontal closed orbit deviation in single bunch operation mode, taking full advantage of the newly installed high resolution BPM electrons system. The current results are compared with those of the previous measurements.
