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]

37-inch cyclotron. Converted cyclone sump (sea sump). Final conversion to 0-degree collection, pre-Helen experiment (Q-trap, with top removed). Photo taken 1/11/1945. 37"-207. Principal Investigator/Project: York
