Beamline 5-BM-C: Sector 5 - Bending Magnet C Branch Beamline

DND-CAT
Materials Science, Polymer Science

Description

The 5-BM-C beamline contains a dedicated high-resolution powder diffractometer and an x-ray tomography system.

The diffractometer is equipped with a Ge(220) analyzer crystal and an Oxford Cyberstar detector. The instrument accommodates both capillaries and flat-plate samples under ambient conditions with a five-position sample changer. User-provided high-temperature furnaces may be accommodated, depending on the device. A displex cryostat can be used to cool one powder sample down to 20 K. The higher energies available on this station allow for the investigation of materials with minimal sample absorption.

Transmission and grazing incidence WAXS measurements using a MAR165 detector can be performed.

The tomography system uses a cryo-cooled CCD system and optics, which permit a range of spatial resolutions from 3 microns to about 24 microns. White beam is also available for sample irradiation studies.
