Description
The Argonne Wakefield Accelerator (AWA) is a 1300 MHz, 65 MeV normal-conducting photoinjector LINAC supporting a broad research program in high-gradient RF acceleration, beam physics, and AI/ML-based accelerator operations. The facility produces electron bunches span-ning 1 pC to 100 nC, including high-charge (~100 nC, ~25 kA), high-brightness (~hundreds nm emittance), and arbitrarily shaped formats, and delivers beam to 5 device-under-test zones along two primary experimental beam-lines.
Over the past decade the AWA has undergone exten-sive modernization, including replacement of the drive gun with an RF-symmetrized photoinjector; upgrade of the drive laser from a 248 nm excimer to a 262 nm Ti:sapphire system; transition to a distributed EPICS-based control system; and deployment of a digital LLRF system developed by the LBNL BACI group. Recent experiments have demonstrated accelerating gradients >300 MV/m in X-band structures, peak cathode fields >400 MV/m, and beam-driven RF power generation >565 MW.
Near-term plans include RF-symmetrized linac cavity replacements and an asymmetric EEX beamline upgrade. A proposed AWA-II upgrade would double the beam energy to ~130 MeV, further expanding the facility’s reach for high-gradient RF and beam physics research.
