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.

At the Tritium Laboratory of the Forschungszentrum Karlsruhe (TLK) an experimental facility is running which is designed for the intercomparison of several hydrophobic catalysts for use in an liquid phase catalytic exchange (LPCE) column. The catalysts under comparison are from Russia, Belgium and Romania. The intercomparison is being performed by computing the height equivalent of theoretical plates (HETP) and the mass transfer coefficients for HD transfer from gas to water using the measured values of the composition. The range of HD concentration in hydrogen as carrier gas was 1000 ppm up to 2%. The gas and liquid composition at the bottom and at the top of the column and the condensed vapour composition at the top of the column are measured by mass spectrometry and IR spectrometry.
