AnImaX endstation

Scanning X-ray microscope using a zone plate for focussing, an Quad SDD detector for fluorescence imaging and a phosphor sceen CCD camera for transmission.

The AnImaX endstation is used for X-ray microscopy in the soft and tender X-ray range. Its movable and flexible design allows the operation at several synchrotron beamlines and a quick change of the full field (TXM) mode to the scanning mode (STXM).

It is equipped with 4 3-dimensional piezo scrawlers to align the optical devices and the sample to the optical axes. For tomography the sample stage can be rotated and a precise 3-dimensional piezo scanner is used for STXM.

In STXM mode a 4-channel SDD is used for lateral resolved X-ray fluorescence analysis.
