The Frisch-Peierls memorandum: A seminal document of nuclear history
The Manhattan Project is usually considered to have been initiated with Albert Einstein’s letter to President Franklin Roosevelt in October 1939. However, a lesser-known document that was just as impactful on wartime nuclear history was the so-called Frisch-Peierls memorandum. Prepared by two refugee physicists at the University of Birmingham in Britain in early 1940, this manuscript was the first technical description of nuclear weapons and their military, strategic, and ethical implications to reach high-level government officials on either side of the Atlantic. The memorandum triggered the initiation of the British wartime nuclear program, which later merged with the Manhattan Engineer District.

Effects of electrode shape on fusion reaction rate in the cylindrical IECF device are investigated by the experiments to verify simulation results. The effects of the cylindrical edge of anodes are clearly observed, but the effect of cathode length and radius is not clear in the preliminary experiments. The maximum neutron generation rate of ~47 thousand neutrons per second is obtained with 37.5kV, 6mA discharge using an anode with 40-mm depth edge.
