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.

The TPX configuration has progressed since the March, 1993 Conceptual Design Review (CDR). Changes have been made to enhance operating performance and improve engineering design margins. Clearances have been added to subsystem envelopes to increase fabrication space and expand assembly tolerances; design modifications have been adopted to meet changes in physics requirements and to enhance maintenance features. Configuration details of magnet leads and services have been added and major subsystem clearance requirements for assembly/disassembly have been revisited.
