(a) Calculated brilliance for the odd harmonics 1–17 at 500 mA for K between 0.5 and 2.10. Simulations were carried out in SPECTRA (version 10.2; Tanaka & Kitamura, 2001) with Gaussian approximation and storage ring parameters from Table 1. (b) Fifth-harmonic undulator peak measured in the first experimental hutch at 5.2 mm undulator gap and at 250 mA ring current with a corresponding simulated spectrum. |
