The X-ray beamline TPS 02A is making use of the bending magnet source at the Taiwan Photon Source (TPS), which is dedicated to performing full-field hard X-ray projection imaging at micron size spatial resolutions in the photon energy range of 5 - 25 keV. It provides the photon flux >4.2 × 1011 photons·s−1 with energy resolution <1.72 × 10-3, the beam size is 35.5 (H) × 8.5 (V) mm2 and beam divergence is 1.2 (H) × 0.3 (V) mrad2 at the sample position. The microscope is capable of examining anatomical information and internal distribution of microstructures by tuning the energy of the photon source to the absorption edge of the samples through the use of a monochromator. Phase contrast tomography is also available for imaging the fine details of in the morphology of the sample.
