ABSTRACT:
The methods and apparatuses for the control of neutron beams are herewith presented. Through the application of the methods and apparatuses presented one can manipulate various characteristics of neutron beams such as shape, velocity, density, polarization and other traits. In general three sequential operations are performed on the neutron beam, although variations of these steps are described to suit various purposes. First, a neutron beam is passed through a gradient magnet field which causes rotation of the beam in phase space. Second, the spin direction of a neutron beam is reversed through the application of a spin flipper. Third, the neutron beam is compressed in the longitudinal direction of the neutron beam in phase space. This produces a neutron beam having small divergence in phase space. The resultant neutron beam corresponds to a thin dense beam in real space. Variations of this paradigm allow for the manipulation of many characteristics of neutron beams to suit ones purpose.
