Rudolf Jaeckel
Rudolf Jaeckel (born December 14, 1907 in Elberfeld , † January 17, 1963 in Bonn ) was a German physicist who dealt with vacuum technology.
He was the son of the chemist Bernhard Jaeckel (1879–1961) and Thekla Saenger. After graduating from high school, Jaeckel studied at the state secondary school in Aussig on the Elbe . He completed an internship at Felten & Guilleaume in Cologne-Mülheim and from 1927 studied electrical engineering at the Technical University of Hanover . Soon after, he switched to physics at the TH Berlin , where he graduated from Gustav Hertz in 1932 . Due to his political attitude, which was not in conformity with the National Socialists, he had to leave the university and in 1933 became Lise Meitner's assistant at the Kaiser Wilhelm Institute for Chemistry in Berlin-Dahlem. There he determined resonance levels in nuclear reactions with neutrons and received his doctorate in 1934 under Lise Meitner. At the end of the 1930s he became Wolfgang Gaede's research assistant at Leybold in Cologne-Bayenthal, where he dealt with vacuum technology and later became laboratory manager. In 1947 he completed his habilitation in Bonn ( on the theory of the diffusion pump ), became a regular associate professor in 1955 and a full professor of applied physics at the University of Bonn in 1962 .
In addition to vacuum technology and physics, he developed the technique of crossed molecular beams to investigate collisions between neutral atoms and molecules.
He was married to Barbara Fuchs (* 1909), a doctor of physics and daughter of the mathematician Richard Fuchs. His son Klaus (1942–1996) was also a physicist.
The German Vacuum Society awards him a Rudolf Jaeckel Prize in his honor.
