Neutron optics are currently used to define neutron beam properties at the sample position (direction, divergence, energy, resolution, polarization, etc…). Since the primary neutron flux is low, optical devices have to be highly efficient. Main concepts and components for designing the optics of neutron instruments are presented. It includes reflection optics such as neutron guides and...
The construction of the high-flux PIK reactor is coming to the final
stage. Its neutron guide system design is almost frozen and will be
presented in details during the talk. The reasons behind design
choices will also be discussed.
The guide system is fed by 2 beam tubes: one equipped with cold
neutron sources and the other is thermal one. In total 13 cold and 5
thermal instrument will use...
Polarizing neutron optics found numerous applications in polarized neutron techniques. Stacks of bent polarizing supermirrors on thin substrates are used as multichannel polarizers and analyzers (“benders”). Solid state benders were also designed and can be made quite compact. Highly polarized white beam is produced by successive reflections from two polarizing supermirrors/monochromators....
