Abstract
A setup for fast multi-energy X-ray tomography is reported. Projection images of a sample using X-ray beams with energies below and above an absorption edge of an element of interest were recorded simultaneously with a multi-beam detector. The sample was rotated to obtain a data set for tomography. In a proof-of-principle multi-energy tomography experiment with a measurement time of 0.25 s, the neighboring elements Ag and Pd could be clearly distinguished.
