The optimal sample shape for tomography is a cylinder. Try to prepare your samples as close as possible to such shape. An important parameter to be kept in mind during sample preparation is the sample absorption. Strong absorbing samples should be kept as small as possible.
To ensure highest data quality, samples must be stable throughout the entire measurement procedure. Even slight sample instabilities can significantly affect the reconstruction quality. Instability can arise from the reaction of the sample to the X-ray beam (bubble formation, desiccation, etc.), inappropriate sample preparation or fixation method, or from the choice of mounting materials. Consult with your local contact about the best way to prepare your samples to avoid motion artifacts, and possible strategies to minimize radiation-induced damage of your samples.
It would be best if your samples would be mounted on pins, which fit our 3.15 mm sample holder. For precise specification, please consult: Sample holder specifications
Please do not hesitate to contact our beamline technicians (staff website), if you need more details.
