Ulrich Schmidt-Rohr

from Wikipedia, the free encyclopedia

Ulrich Schmidt-Rohr (born May 25, 1926 in Frankfurt (Oder) ; † April 21, 2006 ) was a German nuclear physicist.

Schmidt-Rohr was born in Frankfurt (Oder) in 1926 and graduated from high school at the age of 17. His father is the Germanist and sociologist Georg Schmidt-Rohr . He then studied from 1943 at the Technical University of Berlin , the Technical University of Braunschweig and the University of Heidelberg . Interrupted by the Reich Labor Service , drafting into the intelligence force and working in industry, he completed his studies in 1949 and received his doctorate in Heidelberg in 1953 under the later Nobel Prize winner Walther Bothe on “A spectrometer for fast neutrons and the spectrum of (Raα + Be)”.

He then went to Robert van de Graaff at the Massachusetts Institute of Technology (MIT) , where he first came into contact with particle accelerators . Back in Heidelberg in 1955 he was commissioned as an assistant at the Max Planck Institute for Medical Research to build a new cyclotron , which was completed in 1956 and then headed by Schmidt-Rohr. In 1958 the Max Planck Institute for Nuclear Physics was spun off, where he became department head after completing his habilitation in 1960.

In 1963 he went to the newly founded Institute for Nuclear Physics at the Jülich nuclear research facility as director to build an isochronous cyclotron, which went into operation in 1965. A year later he returned to the Max Planck Institute for Nuclear Physics in Heidelberg as a member of the board of directors, where he stayed until his retirement in 1994.
