[Neutron] Three positions in SANS, strain scanning, and reflectomretry at GKSS

[Andreas.Schreyer at gkss.de]

GKSS operates the Geesthacht Neutron Facility GeNF using the reliable 
medium flux neutron source FRG-1 (http://genf.gkss.de) and is currently 
creating a centre for materials research based on the complementary use of 

synchrotron and neutron radiation. Important topics of our applied 
research are, among others, the investigation of lightweight structural 
materials by diffraction (strains, textures) and tomography as well as 
metallic and polymer nanostructures by small angle scattering and 
reflectometry. In the framework of a strategic collaboration with the HGF 
institution DESY (Hamburg) we are operating a synchrotron beamline for 
high energies at the storage ring DORIS III and are building a further 
Beamline
at the new storage Ring PETRA III at DESY. 
In addition we operate a growing outstation at the new neutron 
source FRM II in Munich currently focussing on neutron reflectometry and 
texture analysis and in future also on small angle scattering and 
potentially on
strain scanning. In this framework we have three openings:

One of the most outstanding instruments at GeNF is the SANS-2 instrument 
which is 
mainly dedicated to neutron small-angle scattering studies in materials 
science. 
SANS-2 is complemented by the double crystal diffractometer DCD which 
extends the 
accessible size range to larger structures. In this framework we are 
looking for a 

Scientist (Postdoc)   -   Code-No. W 6

(initial thee year contract)who will have a leading role in operating and 
further 
developing the two instruments SANS-2 and DCD.

In this position you will support external users during experiment, 
evaluation and publication 
of results and deal with orders from industry. This position will allow 
you to develop your 
own scientific program taking advantage of the potential of our research 
center. Within this context, 
international collaborations as well as cooperation with staff members and 
other scientists 
at GKSS are highly encouraged.

In addition we are looking for a

Scientist (Postdoc)  -  Code-No. W 9

(initial three-year contract) in the field of residual stress analysis 
with diffraction methods. You will be responsible for one of our neutron 
diffractometers for residual stress analysis. In this position you will 
take care of external users of our facility at Geesthacht as well as deal 
with scheduled orders from industry. Opportunities for gaining additional 
qualifications by cooperation with internal partners, especially in the 
field of joining techniques, are available. Current topics in this field 
are friction stir welding as well as laser beam welding for aircraft 
construction. In addition, you will also deal with fundamental problems of 

diffraction-based stress analysis. Ideally, you already have a working 
knowledge in the mechanics of materials and experience with diffraction 
methods for residual stress analysis.


Furthermore, we are looking for a

Scientist (Postdoc)  -  Code-No. W 10

(initial three-year contract) in the field of nanomagnetism who should 
have experience with polarised neutron reflectometry and diffuse 
scattering which are used for the study of vertically and laterally 
structured magnetic and non-magnetic nanostructures. You will be 
responsible for one of our neutron reflectometers in Geesthacht with the 
mission to take care of external users. In addition you will be integrated 

into exciting research efforts in the fast moving field of nanomagnetism 
in cooperation with external partners.

A fast familiarization with new topics is a personal challenge for all of 
you. Use of complex experiments and control software is no challenge for 
you. Your English communication skills are good; German language skills 
are an asset. You have adopted a purposeful and result-oriented way of 
working and are able to realize this in a team. You are flexible and 
communicative in your approach with collaborators and you give priority to 

the success of a project and your team. You are used to publishing the 
results of your work and presenting them at international conferences.

A Ph. D. or equivalent in a field relevant to one of the research areas 
listed above (e.g. physics, materials science, crystallography, chemistry 
?) is mandatory. We offer an appropriate salary, related to TV-AVH as well 
as 
the usual public sector social benefits.

The GKSS is an equal opportunity/affirmative action employer seeking to 
increase the proportion of female faculty members. 
Qualified women are therefore especially encouraged to apply.
Handicapped persons with equal qualifications will be preferred.
