Neutron imaging systems and methods

A compact neutron imaging system comprising:

• a) a central neutron source assembly configured to produce source neutrons, wherein said central neutron source comprises a solid or gas target,
• b) a moderator/multiplier assembly,
• c) one or more thermal neutron collimators that extend outward from the moderator/multiplier assembly, wherein each of said thermal neutron collimators is configured to collect a portion of said source neutrons and produce a thermal neutron imaging beam line, and
• d) one or more fast neutron guides that extend outward from said moderator/multiplier assembly configured to collect a portion of said source neutrons and produce a fast neutron imaging beam line.
