The spin-echo SANS (SESANS) working group is a subgroup of the canSAS Reproducibility and Reliability Working Group.

Mission

Spin-echo small-angle neutron scattering (SESANS) is a variant of small-angle neutron scattering that uses the Larmor precession of polarised neutrons to study the structure of materials in real space and up to length scales of some ten micrometer.

The mission of this group is to achieve SESANS measurements that provide data on an absolute scale independent from the used instrument. They do this by discussing the development of standard calibration samples and considering issues of reproducibility between different instruments, ensuring that data are trustworthy, reliable, and comparable.
