The workshop series on future light sources is the flagship event of the ICFA sub-panel on Future Light Sources. It intends to review and discuss modern accelerator-based light sources for wavelengths ranging from the Infrared to X-rays. Working groups will be dedicated to critical issues of ERL, FEL, storage ring and novel light source concepts, as well as to essential technologies like linacs, undulators, synchronization, electron sources, beam diagnostics and numerical simulations. The workshop program will consist of plenary talks and working group sessions.
