The detailed diagnostics of the shortest beam pulses in free-electron lasers still pose significant challenges to beam instrumentation. Electro-optical methods are a promising approach for the non-intercepting measurement of electron bunches with a time resolution of better than 50 fs, but suitable optical materials need to be better understood and carefully studied. In addition, adequate timing systems with stability in the fs regime based on mode-locked fibre laser optical clocks, and actively length-stabilised optical fibre distribution require further investigation. Within the EU-funded LA³NET project these important problems are being addressed by an international consortium of research centres, universities, and industry partners. This contribution gives an overview of the LA3NET project and results from initial studies in both areas. It also describes the events, such as schools, topical workshops and conferences that LA3NET will organize.

  Monitoring and subsequent optimization of electron Linacs and transfer lines requires specific instrumentation for beam position data acquisition and processing. Libera Single Pass E is the newly developed instrument intended for position and charge monitoring in basic and multi-mode operation LINACs. Development, initial measurements and verification of the instrumentation performance were conducted in the Instrumentation Technologies' laboratories, followed by the characterization measurements of the unit carried out at KEK Linac facility.
