Measured spectra of insertion devices W70 (20.1 mm), U46 (16.4 mm), U26 (17 mm) and U20 (16.3 mm) at the ID09 beamline (ESRF, Grenoble, France). Spectra are measured by scanning the monochromator and measuring intensity through a 0.2 mm × 0.2 mm pinhole at the sample position by a PIN diode. Spectra are corrected for the wavelength response of the diode used for intensity measurements. |
