Investigation of source point instabilities in dipole magnet based beamlines

IPAC 2013: Proceedings of the 4th International Particle Accelerator Conference (2013) 3055-3057

M Apollonio, R Bartolini

At Diamond the source point in the second dipole of the Double Bend Achromats (DBA) can vary due the lack of adjacent BPMs constraining angle and position of the electron beam at the dipole. We have implemented a code based on our AT model to predict the effects of a corrector strength change and compared our predictions to data both from a beamline and from our pinhole cameras. We discuss the possibility of interfacing the code to a ray tracing routine in order to infer beam spot changes in the downstream beamline and suggest a procedure to restore the original source point.
