2023 Workshop on Fixed Field Alternating Gradient Accelerators (FFA'23)

10 Sept 2023, 08:30 → 15 Sept 2023, 17:30 US/Eastern

CEBAF Center, CC F113 (Jefferson Lab, Newport News, VA 23606 USA)

The workshop seeks to continue the development of fixed-field accelerators following research in Japan, North America and the UK and to extend the potential range of applications of FFA accelerators. The format will be invited and contributed talks interspersed with periods of focused discussion. The workshop will be preceded by a two-day training school held at JLAB as well, aimed at introducing students (and others) to basic FFA ideas and provide background knowledge leading into the workshop proper.
