Argonne Wakefield Accelerator Facility
In order to achieve the high accelerating gradients needed to produce the tremendous energies required by a future particle accelerator, scientists have been looking for new ideas and solutions. Wakefield acceleration offers a potentially bold new path for the construction of the next generation of particle accelerators.
The Argonne Wakefield Accelerator (AWA) Facility is a resource unique to U.S. Department of Energy. The AWA relies on dielectric two-beam acceleration, a concept that was first demonstrated at Argonne and is now being developed into a practical compact accelerator techology. Plans to test the main acceleration structures at 200-500 MV/m at the AWA facility are underway.
Work at the AWA facility includes the generation of a flexible, gigawatt-scale drive bunch train and the associated diagnostics in the space-charge dominated regime; temporal electron bunch shaping and ring-beam generation both required for high transformer ratio; and emittance preservation issues such as beam break-up control of the drive beam in wakefield structures.
