The high energy materials science beamline will be among the first fourteen beamlines
planned to be operational in 2009 at the new third generation synchrotron light source
Petra 3 at DESY, Germany. The operation and funding of this beamline is assured
by GKSS. 70 % of the beamline will be dedicated to materials science. The remaining
30 % are reserved for physics and are covered by DESY. The materials science activities
will be concentrating on three intersecting topics which are industrial, applied,
and fundamental research. The beamline will combine three main features: Firstly, the
high flux, fast data acquisition systems, and the beamline infrastructure will allow to
carry out complex and highly dynamic in-situ experiments. Secondly, a high flexibility
in beam shaping will be available, fully exploiting the high brilliance of the source.
Thirdly, the beamline will provide the possibility to merge in one experiment different
analytical techniques such as diffraction and tomography.
For the insertion device a five meter long in-vacuum or cryogenically cooled in-vacuum
undulator is under discussion. It will have a main energy of 120 keV, tunable in the
range from 50 to 300 keV and optimized for sub-micrometer focussing. The aim is to be
highly flexible in beam shaping and focussing down to spot sizes far below 1 micrometer.
The implementation of a Kirkpatrick-Baez microfocussing X-ray mirror system
(KB-mirrors), Compound Refractive Lenses (CRLs), a fixed exit monochromator, and
a single-bounce monochromator is planned.
Two experimental hutches will be available. In the first one a high resolution microstructure
and strain mapper and a diffractometer for physics experiments is foreseen.
Furthermore space for user provided experiments and optics will be available.
In the 12 m long second experimental hutch a diffractometer for loads up to 1 t and a
smaller, high precision diffractometer, and a detector portal are projected. Furthermore,
a tomography setup will be placed at the end of this hutch.
