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.

This paper describes the effect of conducting plates installed in the transition region of the minimum-B anchor-cell of GAMMA 10 for the purpose of the improvement in plasma performance. The conducting plates are fixed closely to the plasma surface where the cross section of the plasma is flatly elongated in the transition region. Electrical characteristics of the conducting plates are investigated by changing the resister connected between the plates and the machine ground. Effects on the plasma parameters of the conducting plates are studied and it is found that the floating condition of the plates leads to the increase of the plasma density during potential formation. It is also find that the effect is reduced in the case that the space of main plates facing each other is widened. Existence of electric current in azimuthal direction of plasma cross section is discussed from the viewpoint of radial loss mechanism.
