How to find neutron?

Excuse me, could you please elaborate on the process of finding neutrons? I understand that neutrons are subatomic particles present in the nucleus of an atom, but I'm curious about the specific methods used to detect and identify them. Are there specific instruments or techniques employed in the scientific community to locate and study neutrons? Additionally, what kind of environments or contexts do these techniques typically apply to? I'm eager to learn more about this fascinating aspect of physics.
