24A is a full-field transmission soft X-ray tomography beamline. Microscopy includes an on-line correlation of fluorescence structured-illumination microscopy (SIM) with soft X-ray tomography (SXT), which is dedicated to image frozen-hydrated biological specimen with a spatial resolution of 15-30 nm for 2D imaging and 50 nm for 3D tomography.

To image 3D cellular strustures by the correlation of fluorescence structured-illumination microscopy with soft X-ray tomography.
