Global beam-based alignment method

By: Terebilo, A.;

2003 / IEEE / 0-7803-7738-9


This item was taken from the IEEE Conference ' Global beam-based alignment method ' This paper presents an algorithm for orbit centering in the quadrupole magnets developed specifically for the early commissioning stage of SPEAR3 light source. During commissioning many factors can reduce the effectiveness of simpler beam-based alignment techniques. Our method is more tolerant towards inaccurate optics model, undetected large alignment errors, systematic errors and faults in the BPM system.
