Abstract
In order to prepare for the potentially negative influence of insertion devices (IDs) on beam lifetime, injection effi- ciency and beam size in the MAX IV 3 GeV storage ring, a strategy for neutralizing the foreseen effects of the IDs has been developed. The strategy involves a local correction of the betatron phase advance by adjusting the strength of the quadrupoles adjacent to the ID as well as a global tune correction in order to avoid drift of the working point of the storage ring during operation. Air coils with empirical feed forward tables for the excitation current will compen- sate for field integral errors. The lattice of the MAX IV 3 GeV storage ring appears to be robust and it tolerates the dynamic multipoles created by the... (More)
