NUFACT2017 is the nineteenth in the series of yearly international workshops which started in 1999 and which until now was called International Workshop on Neutrino Factories. The change of name to International Workshop on Neutrinos from Accelerators is related to the fact that the workshop program has, over the years, come to include all current and future accelerator and also reactor based neutrino projects, including also muon projects, not only the Neutrino Factory project.
The main goal of the workshop is to review the progress of current and future facilities able to improve on measurements of the properties of neutral and charged lepton flavor violation, as well as searches for new phenomena beyond the capabilities of presently planned experiments. The workshop is both interdisciplinary and inter-regional in that experimenters, theorists and accelerator physicists from the Asian, American and European regions share expertise with the common goal of reviewing the results of currently operating experiments and designing the next generation of experiments.
