60-inch cyclotron with Milton White and his reflection. August 23, 1939. Cooksey 44. Cooksey note: Looking from above at the "east" side, one sees, below the union of the two dee support tanks, the high speed (approximately 5000 L/sec) oil diffusion pump developed in this laboratory. Professor Milton G. White is by the magnet. Some of the equipment with which Alvarez and Cornog discovered helium three is behind White. Paint cans full of water are piled in front of the control room to reduce the radiation at that point. [Photographer: Donald Cooksey]
