Semi-quantum mechanical explanation
The incoming beam has a polarisation perpendicular to the magnetic field in the precession regions. In the field one can consider the wave…
Gratings
In the figure we show SESANS measurements on a silicon line-grating with a period of 12 mm, a ridge height of 40 mm and a ridge width of 4…
Classical Larmor precession explanation
SESANS uses the usual principles of neutron spin echo to encode the scattering angle of the neutron irrespective of the collimation of the…
SANS
Small-angle neutron scattering SANS is a powerful technique to study the structure of opaque materials at size ranges of nanometers to 0.1…
SESANS by modulation
With minor modification of the SESANS -instrument we obtained a modulated beam. This was achieved by carefully tuning the strength of the…
SESANS
Spin-echo small-angle neutron scattering One of the major projects over the past years has been the development of the spin-echo small-angle…
About the bachelor programme Nanobiology - Erasmus University Rotterdam (Erasmus Medical Centre) and TU Delft
Nanobiology uses the language of mathematics within the context of physics to understand the complexity of biology. Unique to this…
The Ebeam
Most charged particle beams use magnetic fields to transport and focus the beam from the source to the sample. To produce the magnetic field…
