Conference paper


The original planning of the program for making precision energy measurements of nuclear reaction products at M. I. T. can perhaps be traced back to 1939. At that time plans were made for the construction of a magnetic spectrograph of the type built by Cockcroft 1 and used by Rutherford and his collaborators2 in their early measurements on the deflection of radioactive alpha emitters. Two one-ton cylindrical sections of Armco iron were procured in 1940 but, because of the interruption brought about by the Second World War, the design and construction of the 180-degree focusing magnet were delayed until 1945.
