Figure 3
Beam size (a) and spectral distribution (b) of the monochromatic 58 keV beam at the focus. The beam was scanned with a 0.05 mm slit (a). The FWHM was 0.35 mm when the storage ring current was 80 mA, and this increases to about 0.5 mm when the current is 200 mA. The energy distribution was analysed by a vertically reflecting perfect crystal at three locations of the focused beam. The FWHM at a given point is 7.5–9.0 eV, and the total span of energies in a 0.3 mm-wide beam is 29 eV.
