Our Bruker D8 Advance diffractometer includes a vertical theta/theta goniometer with independent rotation of the x-ray tube, x-ray detector, sample stage tilt and spinning. The D8 employs a multiple configurations which can be easily selected from the instrument control software between three main options via Bruker’s TRIO optics:
- Line focus Bragg Brentano configuration using programmable divergence slits.
- Line focus parallel beam configuration using a Goebel x-ray mirror in the primary optics.
- Line focus high-resolution configuration with a Goebel x-ray mirror and a double-bounce Ge(004) monochromator (“channel cut configuration”) in the primary optics.
An optional point focus configuration using pinhole configuration is also available.
All major x-ray diffraction (XRD) and reflectivity (XRR) applications are available in this system.
The system uses the Eigher2 R 500 K detector with 75 microns pixel size, with a total of 1,030 x 514 pixels, with 2.5x108 photons per sec per mm2 capacity. The detector can be used in 0D (point detector), 1D (line) or 2D (areal) modes which are easily selected and configured using the instrument control software.
