Description
The beam lifetime is critical for the synchrotron radiation light source storage rings. By increasing the coupling of the storage ring, the beam lifetime can be improved. However, due to the increased coupling, the beam size around the entire ring also increases. A larger beam size degrades the performance of synchrotron radiation from insertion devices in the straight sections. By using skew quadrupoles to excite vertical dispersion bumps in the arc sections, the vertical emittance as well as coupling can be increased. In this way, the coupling can be localized by minimizing it in the straight sections. This improves the beam lifetime while not affecting the synchrotron radiation from the insertion devices. In this paper, simulations of utilizing vertical dispersion bumps to improve beam lifetime for the ZIPS storage ring is presented.
