EAJADE is a training and staff exchange network for accelerator R&D within elementary particle physics, with a focus on future Higgs factories (as prioritized by the latest update of the European strategy for particle physics) and related technologies. EAJADE addresses the need of exchange of ideas on R&D and implementation of such a future accelerator, on generic technical developments, and on investigations into new and sustainable technologies. EAJADE does so by exchanging accelerator scientists and experts between Europe, America (Canada and USA), and Japan. The project is funded by the EU's Horizon-Europe programme and grant agreement number 101086276.
