From November 25 -28th, ASTeC was host to the final annual review meeting of the EC-funded TIARA Preparation Phase, whose remit has been to substantiate integration of national and international accelerator R&D infrastructures into a single distributed European accelerator R&D facility with the goal of developing and strengthening state-of-the-art research, competitiveness and innovation in a sustainable way in the field of accelerator Science and Technologies across Europe. With 52 attendees from across Europe’s leading laboratories, the main purpose of this concluding meeting was to review the progress within the various TIARA Work Packages and finalise the results of the TIARA Preparatory Phase. For the past 3 years, ASTeC has played coordinating roles as part of collaborative workpackage teams; with Peter McIntosh representing ASTeC in WP3 to develop Accelerator R&D Infrastructures and Susan Smith in WP4 to assess Joint R&D Programming.
