The mission of the RF Accelerator Research (RFAR) Division is to develop next‐generation particle accelerator systems such as structures, sources and auxiliary components that will dramatically increase acceleration gradients and system efficiency, while decreasing system cost, to enable new science and technology applications. RFAR Division develops structure-based “compact accelerator” technology, RF accelerators, and sources that dramatically improve the current state-of-the-art technologies for a variety of scientific applications.

The success of this mission requires simultaneous progress on three fronts:

1. Advancing novel high‐gradient accelerator structures with topologies and materials optimized for high efficiency and low cost of manufacturing.
2. Developing advanced phase and amplitude-controlled power sources spanning the frequency range from RF through THz.
3. Designing integrated accelerator systems to improve cost and efficiency, including RF energy recovery.
