(a) Photons s−1 (0.1% bandwidth)−1 at 200 mA delivered by 1.6 m U32/U27 undulators over the beamline energy range 5–28 keV. (b) Effect of tapering. Using three tapered U27 undulators, an energy range of ∼1 keV can be achieved at 7 keV. Black: the three U27 undulators are at gap = 11.5 mm, no taper. Green: gaps = 11.0 mm, 11.7 mm and 12.5 mm, no taper. Red: gap = 11.75 mm using a linear taper of 1.5 mm.
