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.

Focusing on beryllium capsules, Los Alamos works toward ignition on the NIF, a first step to fusion power. Theory and experiments are giving us a greater understanding of laser plasma instabilities (SBS and SRS). A 1D Kirkpatrick-Baez microscope with < 1 μm resolution has been designed to observe shock timing. Tetrahedral hohlraum implosion experiments are being executed on Omega with symmetry better than cylindrical hohlraums on NIF. Understanding capsule instability growth, and experimentally testing it, is leading to new designs. The first NIF size beryllium capsule has been built from copper brazed hemispheres. Measurements of DT ice on beryllium show adequate smoothness and temperature cycling can reduce it further.
