Neutron source

A neutron source is something that makes neutrons - particles that are found inside the atoms of most things. Neutrons can be useful because they can do things like help scientists study the structure of an atom or help doctors treat people with cancer. Neutrons can be produced in many different ways, but one of the most common ways is by using a special machine called a neutron generator. A neutron generator takes energy and turns it into neutrons that can be used for various purposes.
