Orbit reconstruction, correction, stabilization and monitoring in the ATF2 extraction line

Abstract : The orbit in the ATF2 extraction line has to be accurately controlled to allow orbit and optics corrections to work well downstream. The Final Focus section contains points with large beta function values which amplify incoming beam jitter, and few correctors since the steering is performed using quadrupole movers, and so good orbit stability is required. It is also essential because some magnets are non-linear and can introduce position-dependent coupling of the motion between the two transverse planes. To check the long-term evolution, the orbit is monitored and reconstructed, allowing comparisons with simulations to identify sources of variations.
