This initiative aims at raising awareness on target issues, and at promoting joint efforts to enable high repetition rate experiments and establish sustainable target supply mechanisms for advanced laser facilities. A coordinated action on targets would increase the potential for scientific achievements obtainable at new user facilities and, eventually, be beneficial for the whole community.

These themes were discussed by about 90 users, target fabrication experts and representatives of user facilities in a workshop held in Dresden (August 29–31 2016). An extended summary of the workshop discussions was published on the Journal of High Power Laser Science and Engineering. More at:https://indico.desy.de/indico/event/19890/
