Popis: We have studied a new and reliable cooling method for diamond crystals in third generation light sources. In order to reduce the strain from brazing between the diamond monochromator and its Cu block cooling device, another diamond platelet was introduced as an interface. Using a finite element method program based on numerical thermal analysis, the mounting strain was estimated at 0.6 arcsec. Then data was confirmed through preliminary x-ray characterization using laboratory x-ray sources. The strain in the area exposed to a 1 mm×4 mm synchrotron radiation beam (absorbed power 100 W) was estimated by simulation at an acceptable 1.0 arcsec. Applying the new cooling method, the diamond crystal can tolerate synchrotron radiation power up to 100 W.
