A diamond double-crystal transmission monochromator for the TROIKA II station at ESRF
- Experiments Division, European Synchrotron Radiation Facility, BP 220, 38043 Grenoble (France)
The performance of a diamond double-crystal monochromator for the TROIKA II station at the ESRF was studied. Two (111) oriented diamond crystals for Bragg geometry (120 mm and 500 mm thick) were combined in a nondispersive horizontal scattering geometry and characterized in the white Troika undulator beam. The observed rocking curves were slightly broadened due to nonuniform defect distributions present in the crystals. No heat-load-induced broadening was found. The measured reflectivities compared well to the calculated values, and it was shown that a double-crystal Bragg monochromator can replace a single-reflection Laue monochromator without loss in flux. {copyright} {ital 1996 American Institute of Physics.}
