Samples

Format

Thin films (OD=1, for specific sample calculation see http://www.cxro.lbl.gov/optical_constants/) deposited typically on Si3N4 membrane (similar to TEM substrates) or other x-ray-transparent substrates

Preparation

Sample dependent

Sample environment

External magnetic fields up to 5 kOe in  beam direction and 2 kOe along the sample plane; tilted sample holder for in-plane magnetized samples; He at atmospheric pressure, wet or dry, low temperature (cryo)

Special notes

Mutual indexing system with visible-light microscopy provided to position and focus sample

Scientific applications

Transmission imaging x-ray microscopy for magnetic materials (XMCD contrast), materials sciences, environmental sciences, polymers and biological samples; x-ray tomography for 3-dimensional imaging
