The Y-12 Plant in Oak Ridge used the electromagnetic separation method, developed by Ernest Lawrence at University of California-Berkeley, to separate uranium isotopes.
University Involvement in the Manhattan Project
One of the most important branches of the Manhattan Project was the Metallurgical Laboratory (Met Lab) in Chicago. Using the name "Metallurgical Laboratory" as cover at the University of Chicago, scientists from the east and west coasts were brought together to this central location to develop chain-reacting "piles" for plutonium production, to devise methods for extracting plutonium from the irradiated uranium, and to design a weapon. In all, four methods of plutonium separation were considered, with the bismuth phosphate process displaying the most promise.
Cynthia Kelly: So Don, why don’t you tell us your name and spell it?
Donald Ames: My name is Donald Ames, D-O-N-A-L-D A-M-E-S.
Kelly: Okay, and you should look at me instead of the camera. That’s better. Why don’t you tell us about where you were before the war and how you came to work on the Manhattan Project?
Ames: Okay, I was a farm boy. I went to the University of Wisconsin, where I earned my way through school. Of course, the tuition was only $32 a semester.
