Technical features

TomoLab is a micro-CT system based on a cone-beam geometry. It is equipped with a sealed microfocus X-ray tube, which guarantees a minimum focal spot size of 5 micron, in a voltage range from 40 up to 130 kV, and a maximum current of 300 microA. A water cooled CCD camera providing a good combination between a large field of view (49.9 mm×33.2 mm) and a small pixel size (12.5×12.5 micron2) is used as detector. Due to the cone-beam geometry it is possible to achieve a spatial resolution close to the focal spot size. Wilkins & co. in 1996 have shown that radiographs made using the polychromatic beam from a microfocus X-ray generator do reveal phase jumps. Thanks to this property at the TomoLab it is possible to perform phase-contrast microCT measurements (also if a limited phase contrast with respect to a synchrotron X-ray beam could be achieved).
