Work in progress..  Beam tracking with SAD through ATF combined optics: extraction line and proposed KEK final focus  Three tracking routines (good agreement) Mauro Pivi, Okugi-san, Andrei Seryi

DX (m) BX BY  1/2 (m) SAD: Combined extraction line and final focus

Beam tracking with SAD Not yet combined: only final focus As expected

Beam tracking with SAD All line combined: extraction + final focus DP (%) sigx (m) sigy (m) sigx/sigx0 sigy/sigy E E E E E E E E Is real effect ? Need to re-check combined optics ?!
