Title:

Inside the 60-Inch Cyclotron

Description:

In this 1939 photo, Eric and Margaret Lawrence are sitting inside the tank of something called the 60-inch cyclotron -- a machine invented by their father, Ernest Lawrence. The cyclotron is a unique circular particle accelerator, which Lawrence himself referred to as a 'proton merry-go-round.' In reality, the cyclotron specialized in smashing atoms. Fun facts: this cyclotron contains a magnet that weighs 220 tons, and experiments conducted on this very machine led to the discovery of plutonium and Nobel Prizes for researchers Glenn Seaborg and Melvin Calvin. | Photo courtesy of Lawrence Berkeley National Laboratory.
