| Popis: | Computed tomography (CT) with hard X-rays is a mature technique that is in regular use to depict the interior of opaque specimens with spatial resolutions up to the micrometre range (microtomography or µ CT). Short acquisition times and sophisticated contrast modes are accessible when synchrotron light sources are combined with microtomography&mdash SR-µ CT. Both features render SR-µ CT as excellent probe to study delicate samples in situ, for example under mechanical load by deploying corresponding sample environments. The so-called TomoPress is such a device available within the public user programme of tomography beamline ID19 of the European Synchrotron Radiation Facility (ESRF). It allows one to study samples under high axial load (up to 500 N) with high spatial resolution up to the micrometer range. Different gauges are installed to allow online monitoring of the applied force. Constant humidity, temperature and wetting are routinely available as well. The article shall outline basic design principles of the press as well as parameters for its utilisation in a descriptive manner. Selected examples underline the potential of the device for such diverse fields as biomedical research, life sciences and materials research. |
