Rudolf Kollath
Rudolf Johannes Gustav Kollath (born December 21, 1900 in Hohensalza ; † August 12, 1978 in Mainz ) was a German experimental physicist and professor at the University of Mainz .
Life
Kollath was the son of the mayor of Hohensalza and after graduating from high school in 1918 studied architecture and then physics with Carl Ramsauer at the Technical University of Danzig .
In 1928 he received his doctorate from Ramsauer ( on the vertical deflection of slow electrons on gas molecules ) and followed him to the AEG research institute in Berlin-Reinickendorf, where he stayed until 1941. There he researched the interaction of slow electrons and ions with gas molecules and the passage of particle beams through matter, as well as the secondary electron emission of solid bodies when irradiated with electrons. This was later reflected in articles in the handbook of physics .
During World War II he served as a soldier in Norway.
In 1944 he was with Rolf Wideröe in Hamburg and in 1947 he worked on a betatron in London . In 1948 he completed his habilitation in Hamburg, where he became a scientific adviser and an adjunct professor from 1951 to 1953. In 1953 he became an adjunct professor for experimental physics in Mainz. Later he was director of the 2nd Physics Institute and in 1957 full professor. In 1966 he retired.
He was active in international scientific exchange, for example in setting up research centers in Cairo and in the partner university of Mainz in Bogota, where he was honorary professor.
