==== Low energy nuclear reactions ====
Low-energy nuclear reactions are the basis of neutron production in accelerator-driven sources. The selected target materials are based on the energy levels; lighter metals such as [[lithium]] (Li) and [[beryllium]] (Be) can be used toachieve their maximum possible reaction rate under 30 MeV, while heavier elements such as tungsten (W) and [[carbon]] (C) provide better performance above 312 MeV. These Compact Accelerator-driven Neutron Sources (CANS) have matured and are now approaching the performance of fission and spallation sources.<ref>{{Cite journal |last1=Ashkar |first1=Rana |last2=Bilheux |first2=Hassina Z. |last3=Bordallo |first3=Heliosa |last4=Briber |first4=Robert |last5=Callaway |first5=David J.
