When an artificial neutron source is created, from decay (from ground state or from an excited state resulting from fusion or a photon), or spallation, the trajectory of the emitted neutron is random,right? This would mean that there would be a neutron flux field, following the inverse square law, as opposed to a beam. If this is correct, what mechanisms are used to bunch up the neutrons into a single beam, considering that they are easily absorbed and do not have a charge?
