Comparison of Alignment Tolerances in the Linear Collider Damping with Those in Operating Rings(LCC-0112)

The next generation linear colliders require damping rings to generate beam with very small transverse emittances to attain the desired luminosity. The required emittances are smaller than that of most operating synchrotron radiation sources. In this paper, the alignment tolerances needed to attain these small emittances are compared with those of the operating synchrotron radiation facilities and a prototype damping ring, the ATF at KEK. The concept of this study originated at the Nanobeams Workshop during a discussion in the Storage Rings Working Group although the results were not discussed at that meeting
