Strategy for Neutralizing the Impact of Insertion Devices on the MAX IV 3 GeV Ring

In order to prepare for the potentially negative influence on the beam lifetime, injection efficiency and beam size from the insertion devices (IDs) on the stored beam of the MAX IV 3 GeV storage ring strategy for neutralizing the foreseen effects of the IDs has been developed. In short the strategy involves a local correction of the betatron phase advance by adjusting the strength of the quadrupoles adjacent to the ID. There will also be a global tune correction in order to avoid drift in the working point of the storage ring during operation. Air coils with empirical feed forward tables for the excitation current in the coils will compensate 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 expected initial set of IDs provided that the local correction of the betatron phase advance has been carried out.

A design study of the MAX-IV light source complex in Sweden has been completed. One of MAX-IV's main light sources, a 3 GeV storage ring, is designed to achieve a natural emittance of ~0.2 nm rad. The facility will also provide SASE-XFEL using a 3 GeV high performance linear accelerator. The speaker will discuss facility targets, the concept and accelerator design, and show some possibilities approaching two-dimensional diffraction-limited X-ray generation at MAX-IV.
