PETRA III at DESY
P62 SAXSMAT

The SAXSMAT (Small-Angle X-ray Scattering beamline for Materials Research) beamline P62 is designed for anomalous SAXS/WAXS, SAXS/WAXS computed tensor tomography, In situ and operando SAXS/WAXS as well as high-throughput SAXS/WAXS applications. The X-ray energy range available is 3.5 keV up to 35.0 keV.

The following measurments techniques are availble at the beamline:

Anomalous SAXS/WAXS

The beamline optics has been optimized to allow anomalous SAXS/WAXS experiments and therefore getting element sensitve structural information of the samples. This option of the optics allows EXAFS kind of measuremtents to be conducted at P62.

SAXS/WAXS computed tensor tomography

A special customized sample environment with high-resolution nanopositioniers is available to allow SAXS/WAXS tensor tomography experiments. The spatial resolution of the 3D tomograms is defined by the beam size at the sample position. Currently in the range of 20x20µm².
 

In situ and In operando SAXS/WAXS

Currently, we are developing a furnace that will allow fast heating and cooling of samples in differnet atmospheres as well as in vacuum.
 

High-throughput SAXS/WAXS

Currently, we are developing strategies to handle as much sample as possible (solid and liqued) with less human interaction involved.
 

USAXS

Due to the long tube system and the capability to focus onto the beamstop in front of the SAXS detector ultra small angle X-ray scattering experiments can be performed at P62 with a resolution of  µm.
