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.

We built a precision radiography system that measures shells for all current ablator materials to an accuracy of 1:104 in optical depth fluctuation and a spatial resolution of 120 m. The data obtained by the precision radiography system for undoped shells was compared with the data taken using the well-known surface measurement technique Spheremapper. Since both techniques yielded the same power spectrum for the same shell, the results of the precision radiography system were verified. When this technique is compared to the Be:Cu NIF shell, there is no significant internal layer fluctuation. To account for the growing measurement demand, a new x-ray system to accommodate measurements in 1 working day was designed.
