What is a Calutron?
They were implemented for industrial-scale uranium enrichment at the Oak Ridge, Tennessee Y-12 plant established during the war and provided much of the uranium used for the "Little Boy" nuclear
Spectrometers – scanning, spectrographs, spectroradiometers,
Spectrometers are devices for separating spectral components and measuring them. They can use diffraction gratings or prisms, interference effects or other methods.
Calutron Explained
A calutron is a mass spectrometer originally designed and used for separating the isotopes of uranium. It was developed by Ernest Lawrence during the Manhattan Project and was based on his earlier
