Apparatus to measure the decay of the free neutron. The experiment was designed by Luis Alvarez and was built and tested by Cornelius Tobias for his doctoral thesis in 1941. The project was stopped when the 37-inch cyclotron was converted to isotope separation. Photo taken May 2, 1941. Morgue 1946-8 (P-16); Cooksey 454 [Photographer: Donald Cooksey]

The magnet was adapted for use in a huge mass spectrograph to test the feasibility of Lawrence's plan to separate the fissile, or explosive, part of natural uranium, U- 235, from its much more plentiful companion isotope, U-238. Morgue 1944-98 (P-1) [Photographer: Donald Cooksey]
