===Nuclear fusion systems===
Nuclear fusion, the fusing of heavy isotopes of hydrogen, has the potential to produces large numbers of neutrons. Small scale fusion systems exist for (plasma) research purposes at many universities and laboratories around the world. A small number of large scale fusion experiments also exist including the [[National Ignition Facility]] in the US, [[Joint European Torus|JET]] in the UK, and soon the [[ITER]] experiment currently under construction in France. None are yet used as neutron sources.

[[Inertial confinement fusion]] has the potential to produce orders of magnitude more neutrons than [[spallation]].<ref name=taylor2007>{{cite journal |author=Taylor, Andrew |title=A Route to the Brightest Possible Neutron Source? |journal=[[Science (journal)|Science]] |volume=315 |date=February 2007 |pages=1092–1095 |pmid=17322053 |doi=10.1126/science.1127185 |last2=Dunne |first2=M |last3=Bennington |first3=S |last4=Ansell |first4=S |last5=Gardner |first5=I |last6=Norreys |first6=P |last7=Broome |first7=T |last8=Findlay |first8=D |last9=Nelmes |first9=R |issue=5815|bibcode= 2007Sci...315.1092T|s2cid=42506679 }}</ref> This could be useful for [[neutron radiography]] which can be used to locate hydrogen atoms in structures, resolve atomic thermal motion and study collective excitation of nuclei more effectively than [[X-rays]].
