Brookhaven's ATF and associated test facilities

Brookhaven’s Accelerator Facilities Division provides users with access to a wide range of advanced research capabilities. This includes the Accelerator Test Facility (ATF), which features an RF photocathode electron LINAC, a femtosecond Ti:Sa laser, and a high-peak-power long-wave infrared (LWIR) laser. These tools can be synchronized for joint use or operated individually, facilitating the development of advanced beam manipulation and measurement techniques, accelerator and laser technologies, and the exploration of low-plasma-density regimes. This research supports precise electron seeding into plasma cavities, enabling the production of low-emittance beams for compact laser wakefield accelerators (LWFAs) across various scientific and industrial applications.

Additionally, the division supports the Ultrafast Electron Diffraction (UED) facility, where an RF electron gun and Ti:Sa laser enable dynamic studies of material structures, as well as investigations involving low-energy electron beams. The unique research opportunities available at each of these facilities will be highlighted. Beginning in 2025, access to these facilities will be available through the BeamNetUS program for users from academia, industry, and national laboratories.
