Use of a neutron guide

Cold neutrons of wavelengths longer than 4 angstroms can be extracted and a reflectometer installed for investigating layered structures of polymers. A spin interferometer with multilayer spin splitters can also be installed for investigating spin interference phenomena. Studies of this phenomenon are good subjects for students and young scientists to work on in order to understand the concepts of quantum mechanics (e.g., what the superposed state is). 

The facility is designed to make thermal neutron penetrate in the liquid hydrogen with — 253 C, and

A guided beam of cold neutrons will provide the highest intensity neutron beam with the lowest background at the sample position. Therefore, the use of a neutron guide is desirable. In addition, a pair spectrometer or a Compton suppression system is a desirable option, although this need is decreasing due to better detectors, MCAs and analysis software.
