Fast tomography using quasi-monochromatic undulator radiation
A beamline with a helical undulator has been used without a monochromator for fast high-resolution tomographic imaging with an X-ray energy of 12.4-16.5 keV and an energy bandwidth of 2-3%. The X-ray beam was expanded with two mirrors to 12 mm x 4 mm. The X-ray field was made uniform by a diffuser....

| Résumé: | A beamline with a helical undulator has been used without a monochromator for fast high-resolution tomographic imaging with an X-ray energy of 12.4-16.5 keV and an energy bandwidth of 2-3%. The X-ray beam was expanded with two mirrors to 12 mm x 4 mm. The X-ray field was made uniform by a diffuser. The detector pixel size was 9.9 microm x 9.9 microm. At the highest speed, a 180 degrees scan was completed in 6 s with 454 projections. Beam-hardening effects were not significant. This technique may be useful in studying time-dependent structural changes of soft materials such as polymers and biological samples |
