This extremely versatile multi-resolution X-ray tomography scanner is located at the Laboratory for Wood technology, hence its name. It is equipped with two separate X-ray tubes and two different X-ray detectors to allow for optimal scanning conditions for a very wide range of samples. The open-type Hamamatsu transmission tube is used for very high resolution CT scans, where a resolution of approximately 0.4 micron can be achieved, whereas the closed-type Hamamatsu directional tube head is used for larger samples. On the detector side, an 11 megapixel Photonic Science VHR CCD camera with a pixel size of approximately 7² µm² is complemented with a large-area Varian flat-panel detector. Using 7 motorized linear stages, X-ray tube and detector can be switched with a click of a button, and the scanning geometry can be chosen to optimize the detected X-ray flux or optimize the X-ray propagation distance for phase contrast imaging.
