Accelerator Test Facility

1) The Accelerator Test Facility (BNL-ATF) is a user facility within Brookhaven National Laboratory (BNL) in New York, USA. Commencing operation in 1989, the BNL-ATF carries out research and development on advanced accelerator physics and studies the interactions of high power electromagnetic radiation and high brightness electron beams, including plasma-acceleration and laser-acceleration of electrons.

2) The Accelerator Test Facility (KEK-ATF) is a test accelerator in the KEK laboratory in Tsukuba, Japan. It is a test bed for production of the beam for the proposed International Linear Collider (ILC) linear electron-positron collider. Its main goal is to create the super-low-emittance beam which is needed for the ILC.
