Neutron Sources
a range of different sources can be used:
- A nuclear reactor
- An actinoid such as californium which emits neutrons through spontaneous fission
- An alpha source such as radium or americium, mixed with beryllium; this generates neutrons by a (α,12C+n) reaction
- A D-T fusion reaction in a gas discharge tube

Famous quotes containing the word sources:
“I count him a great man who inhabits a higher sphere of thought, into which other men rise with labor and difficulty; he has but to open his eyes to see things in a true light, and in large relations; whilst they must make painful corrections, and keep a vigilant eye on many sources of error.”
—Ralph Waldo Emerson (1803–1882)
