Figure 2
Horizontal coherent fraction versus emittance [from equations (2)[link] and (4)[link], with ∊r(λ) ≃ λ/2π] for various X-ray wavelengths (top) and electron–photon phase space matching that minimizes convolved emittance (bottom). Dashed curves indicate coherence gain for a 4 m undulator when βx is reduced from 10 m to 1.27 m (= Lund/π).
