The Accelerator Test Facility (ATF) is a proposal driven, Program Advisory Committee reviewed facility that provides users with high-brightness electron- and laser-beams. The ATF pioneered the concept of a user facility studying properties of modern accelerators and new techniques of particle acceleration over 25 years ago. It remains a valuable resource to the user community. ATF serves the U.S. Dept. of Energy Accelerator Stewardship program.Contact Us
Next APAC/ATF User Meeting October 14-15, 2014. Deadline: Proposal applications due September 15, 2014.
High-brightness, 80 MeV, sub-picosecond, 3 kA electron bunches are being delivered to the experimental hall where user experiments are parked in three beam lines. The experiment beam lines are fully equipped with beam manipulation and diagnostic and special insertion devices to support diverse user requirements. The ATF unique capabilities include the possibility to combine the electron beam with synchronized high-power CO2 laser. Stage 1 of the ATF-II upgrade proposal (PDF) has been approved by DOE, Office of High Energy Physics. The electron beam energy will be increased to 150 MeV.
ATF's one-terawatt, picosecond, IR (10 μm) carbon dioxide laser is unique in the world. With it, the ATF users explore long-wavelength scaling of various physical processes and new approaches to particle acceleration and x-ray generation. A next-generation ultra-fast CO2 laser based on chirped pulse amplification in isotopic gas mixtures is under construction. This laser will open the long-wavelength spectral domain to exploring strong-field phenomena at a0=10.
The unique combination of a high-brightness electron beam and high-power picosecond CO2 laser opens unsurpassed opportunities for user exploration of new ideas for advanced particle accelerators and radiation sources.
This diagram highlights variety of user experiments from past and present enabled by the ATF’s e-beam and laser used separately or in their combination. Browse through the Upgrade Proposal pages to learn about ATF’s milestone contributions to the accelerator science and new opportunities for advanced studies after the planned facility upgrade. This upgrade is supported by a BNL Program Development grant and enabled by the DOE, Office of High-Energy Physics.
The Accelerator Test Facility is a member of the National User Facility Organization (NUFO) which represents the interests of all users who conduct research at U.S. national scientific user facilities, as well as scientists from U.S. universities, laboratories, and industry who use similar facilities outside the United States.
