The Semi-Transparent Diamond Monochromator at the ESRF Troika Beamlines

摘要

The Troika beamline ID 10 at the European Synchrotron Radiation Facility(ESRF)provides a high-brilliance X-ray beam from an undulator source to three experimental stations(ID10A,ID10B and ID10C,Figure 1).When the first monochromator was installed in 1997 the X-ray source was composed of 3 undulators in series installed in the high-straight section 10 of the ESRF storage ring.In details,the source consisted of two U42 undulators(magnet period 42 mm,length 1.6 m)and a mini-gap undulator U26(26 mm period).
