Title Towards Polarization Analysis for Quasi Elastic Neutron Scattering (PA-QENS)
Description Polarization analysis provides profound additions in knowledge for the field of soft condensed matter research. The ability to study dynamics of incoherent and coherent scattering contributions separately gives unique information on the cooperative vs local dynamics of a system. The JCNS is interested in exploring new instrumentation ideas as a polarization analysis upgrade to our SHPERES backscattering instrument and new ideas for the proposed High-brilliance Source (HBS). The concepts should consider polarized super-mirror based and polarized 3He based options through neutron ray-tracing modeling (Mcstas or Vitess) and practical work with the techniques. Working towards routine polarized QENS will also require experimental work in soft condensed matter using existing instrumentation and work processing the obtained data to explore concrete applications of polarization analysis in such systems. An ideal fellow would have experience in either neutron instrumentation and neutron ray tracing simulations or (and) dynamics in soft condensed matter research with an interest gaining experience with the other.
