Here is Lawrence and his assistant Don Cooksey at the 60-inch cyclotron which began to operate in 1939 and produced 16 MeV deuterons, and had a magnet weighing about 200 tons. Here is a picture of the deuteron beam coming out of that 60-inch cyclotron, 16 MeV deuterons. Here is a picture of Ernest Lawrence with his brother John, who joined the Laboratory in 1937 to do the pioneering work in nuclear medicine. Really, he was the instigator, the first person to do significant research in nuclear medicine using the radioactive isotopes produced in the Berkeley cyclotrons.
Here's a picture of the group, with all of their names there, at the 60-inch cyclotron. More or less the key personnel at that time in 1939.

Ernest O. Lawrence Nobel Award announcement on blackboard |
On November 9, 1939, word came that Ernest Lawrence had received the Nobel Prize for his invention of the cyclotron. There's an interesting story there. Darleane had mentioned that Helen Griggs was serving as Ernest Lawrence's secretary, and she got the word. He was over at the Claremont tennis court playing tennis. She phoned there trying to get in touch with him, but they said they couldn't bother him. "Yes you can bother him. I want to give him this news." So she was the one who gave him the news on his winning the Nobel Prize. This is self explanatory (referring to the blackboard announcement). This is the celebration that they had there.
