“…Similarly, in 4 th generation synchrotron light sources, where the quadrupole and sextupole magnets have small apertures, the NEG-coating technology proves to be an effective solution to attain low pressures. The Max IV and Sirius are two operating 4 th generation synchrotron light sources whose storage ring vacuum system is fully implemented based on this technology [4]- [5].…”

The current study compares two vacuum system designs for the Iranian Light Source Facility (ILSF) storage ring: conventional vacuum system design with stainless-steel vacuum chambers that are pumped by Non-Evaporable Getter (NEG) cartridges and ion pumps. In this design, all synchrotron radiation is absorbed by the local photon absorbers. In the second design, the water-cooled copper tubes that are coated with NEG materials are used as the vacuum chambers. This study will illustrate the advantages of using the NEG-coated vacuum chambers over the conventional design with the stainless-steel chambers. Since the two designs for ILSF are now completed, some of the details of this comparison might be interesting to other light sources, especially those that have plans to upgrade to a 4th generation.
