Objective
The most sophisticated and informative neutron techniques use the 3D vector nature of the neutron polarization. Collaborative activities of the project are directed to exploring new possibilities of two such techniques, Neutron Spin Echo (NSE) and Polarized Neutron Reflectometry (PNR) extended by 3D polarimetry. Both, NSE and PNR, techniques are at the forefront of condensed matter research. The dynamical processes studied by NSE play a key role in shaping the basic physical properties of high-tech materials. NSE becomes more and more important for the study of slow dynamics in different fields where further technological breakthroughs may be expected. In its turn, PNR is now recognized as playing a crucial role in tackling problems of surface and layered structure magnetism with very promising technical applications. Themes A and B specify the directions of the efforts to be undertaken. A. Development of NSE techniques exploiting multilevel neutron states. The main objectives: - to develop a multiwave Neutron Resonance Spin Echo method allowing one to directly measure the many-point correlation functions; its application to measurement of the triplet correlation functions; - to study the neutron multiwave interference by using the Ramsey's resonance method of separated oscillating fields; application of the multi-resonance coil system for modelling elementary quantum computing operations; - to build up a bunching system and demonstrate the potential of the new method of bunching at a sub-thermal neutron beam line; - to evaluate by computations the optimum Wanderfeld shape of the field for TOF imaging and to design the respective current distribution system. B. Development of approaches and methods of direct reconstruction of the depth profiles of the nuclear scattering length and magnetization. The main objectives: - to study the technical possibility of 3D polarimetry without wavelength-dependent spin manipulators for white beam applications on the basis of remanent systems; - to study experimental and instrumental approaches to polarized neutron phasometric reflectometry of magnetic layered structures, including those which are alternative to the strategy of the spherical polarimetry; - to study the potential of specular reflection mode of SESANS for extending the application range and improving the spatial resolution of a first principles inversion in phasometric reflectometry; - to develop "single-sample" methods for reconstruction of scattering length profiles with polarized neutron reflectometry: the reference techniques with variable liquid surroundings and the alternative approaches, in which the available information about the magnetic sample is used. The results of theoretical and experimental studies may open new fields of polarized neutron research, allowing important physical information to be obtained, inaccessible by other experimental techniques.
