Horizontal natural emittance (∊x, blue) and storage-ring circumference (C, green) versus electron-beam energy of a representative ensemble of existing third-generation synchrotron light sources (Feikes et al., 2004) (BESSY II, ALS, Elettra, ALBA, Soleil, Diamond, SLS, TPS II, SSRF, APS, ESRF, SPring-8). Lines are fits to the experimental values as discussed in §2.2. |
