Final EuroNNAc and EEAC Report

This report presents a short summary of the outcome of work progress in the tasks of the European Network for Novel Accelerators (EuroNNAc) and the status of European strategies for plasma accelerators and dielectric accelerators. The European Advanced Accelerator Concepts workshops were held in 2017 and 2019, they serve as a growing forum for discussions and coordination of activities and are reported on. The WP5 work led, amongst others, to the advance of a new European research Infrastructure EuPRAXIA, coordinated input to the European Strategy for Particle Physics and finally to the recent formation of a European Expert Panel for the contribution of this field of science to Particle Physics
