Beams PY 2010 BP 042801 EP 10pp VL 13 IS 4 DI 10.1103/PhysRevSTAB.13.042801 LA English AB ATF2 is a final-focus test beam line which aims to focus the low emittance beam from the ATF damping ring to a vertical size of about 37 nm and to demonstrate nanometer level beam stability. Several advanced beam diagnostics and feedback tools are used. In December 2008, construction and installation were completed and beam commissioning started, supported by an international team of Asian, European, and U. S. scientists. The present status and first results are described. ER
