Description
The Argonne Wakefield Accelerator (AWA) is a beam test facility with a core mission of advancing structure wakefield acceleration (SWFA) technologies for future high-energy linear colliders, compact FELs, and related applications. It supports both Two-Beam Acceleration (TBA) and Collinear Wakefield Acceleration (CWA) by producing diverse electron bunch formats, including 100 nC bunches with peak currents >25 kA, longitudinally shaped bunches, and THz-rate bunch trains.
In the past five years, AWA has demonstrated key SWFA concepts, including TBA short-pulse RF acceleration near 0.5 GV/m and CWA with high efficiency (transformer ratio >5). Recent milestones include dielectric and metamaterial wakefield structures, advanced bunch shaping via emittance exchange and laser methods, and machine learning tools for 6D beam diagnostics.
The proposed AWA-II energy upgrade will support a 500-MeV demonstrator toward a 10-TeV e⁺e⁻ collider and a 1-GeV water-window FEL. AWA also enables broad accelerator R&D, including bright beam production and beam physics studies, with a strong mix of in-house and collaborator-led projects and a proven record in workforce development and interdisciplinary collaboration.
This upgrade will ensure AWA remains a versatile, high-impact platform supporting multiple national roadmaps and research priorities identified by U.S. funding agencies and community panels.
