The FCXR facility has a length of 2059 mm from X-ray generator to detector. The X-rays are generated with a copper rotating anode emitting a continuous Bremsstrahlung spectrum. The monochromator, composed of asymmetrically cut germanium crystals, is designed for passing Cu k-alpha (8.047 keV). The detection of the photons is acquired with a custom built linear positional sensitive detector or similar. The X-ray beam may be shaped into multiple dimensions ranging from 0.1 mm x 0.1 mm – 5 mm x 5 mm (heigh x width) by slits before impinging the sample. Samples with dimensions up to 200 mm in length and 300 mm in height can be mounted in the setup.
