ATF2 S.Kuroda( KEK ) Introduction to ATF2 Project Hardware Status Software Status Commissioning of ATF2 Future Plan Introduction to ATF2 Project LC final focus test beam line at KEK-ATF Reference: ATF2 proposal, KEK report 2005-2, 9 Home page: http://atf.kek.jp/collab/ap/projects/ATF2/index.php Phase1.( to be done by 2010 ) Goal: Achievement of small beam size as ~35nm, and maintaining it for a long time. Requirement: y=310-8m in DR Phase2. Goal: Stabilization of beam position within a few nm. Requirement: High resolution BPM & FB Fast Kicker(FK) for ILC-like bunch structure Experimental Test of Beam Delivery System( BDS ) FFTB( SLAC ) 1994 Traditional chromaticity correction scheme ( SX pairs with -I transfer matrix in between ). Beam size of 70nm observed for several hours. ATF2 Local chromaticity correction scheme ( miniature of ILC design ).
