DISCLAIMER: This thread is a repost of another thread in the Nuclear/Particle Physics forum since I cannot delete that thread but this forum is more appropriate since it is more of a question in Nuclear Engineering than in Nuclear Physical theory.
So I have been reading about the operational principles of compact neutron generators(which use fusion, either D-D or D-T). And apparently all of the types mentioned generate isotropic neutrons by accelerating deuterium ions into a target containing lithium deteuride or a metal plate coated with tritium. Now I also realize that neutrons, having a magnetic moment, can be deflected and focused into a beam using a hexapole magnetic lens.
So So this is the question I have for you experimental nuclear physics wonks: If a neutron source like the one I described has the deuterium beam target enclosed in a cylindrical magnet with an antiparallel magnetic field, does the constraint of the magnetic field have any effect on the direction of neutron emission? That is, can this technique be used to force neutrons emitted from the fusion reaction to flow outwards away from the target plate instead of isotropically in all directions? If this does not work, how else can a focused beam of neutrons be produced so that they can be collimated into a directional beam?
