Experimental physicist or physical chemist
The development of the new SANS technique, spin echo SANS (SESANS) is
part of the FOM-programme for Technical and Phenomenological physics.
SESANS promises to become a big expansion in the possibilities of
measuring techniques in mesoscopic physics. The technique uses the
precession of polarised neutrons in magnetic fields. The spin-echo of
the precession yields detailed information on structures in mesoscopic
systems on characteristic distances of 5 nanometer up to microns.
Furthermore, the expectation is that the new technique gives the
information in measuring times of seconds or minutes which is extremely
short compared to conventional SANS. This technique can be applied in
studies of structural phase transitions in metals, structures in
colloidal particles and other mesoscopic systems as polymers and
You will participate in the SANS research programme of this group or in
the programmes of the user group for the new SESANS instrument. These
are structural studies into the phase behaviour of polymers, colloids
and food materials in collaboration with the universities of Groningen
and Utrecht and the NIZO and Unilever. The SANS measurements will be
performed on the new SESANS-instrument and on SANS-instruments at other
European neutron sources. Intensive collaboration with scientist from
the Netherlands and abroad are an important part of your PhD.
The department of neutron scattering and Mössbauer spectrometry
investigates the properties of solid state materials (e.g. polymers,
magnetic material and catalysts) by measuring their transmission and
scattering of neutrons and gamma rays. The department has its own
facilities for these measurements. Many measurements are performed at
facilities in France, the UK and Germany.
The research group Instrument Innovation investigates new methods of
neutron scattering with polarised neutrons: small angle neutron
scattering (SANS), high-resolution neutron diffraction and neutron
We are looking for a technical interested experimental physicist of
physical chemist with interest in the physics of mesoscopic systems.
Experience with scattering techniques would be an advantage.
Conditions of employment
As a PhD-student you will get a position at the FOM-foundation for 4
years. During the first year the gross salary is fl. 2470,- per month.
This amount will increase to fl. 4199,- during the fourth year. During
the first three years an additional allowance is paid of respectively
