Joachim Ullrich (*1956 Edenkoben) received the Gottfried Wilhelm Leibniz Prize for his work in the area of Experimental Physics.
Joachim Ullrich studied experimental physics at the University of Frankfurt am Main, where he also went on to earn his PhD at the Institute of Nuclear Physics in 1987 and his habilitation in 1994. He was appointed to his current chair at the University of Freiburg in 1997. He spent the intervening years working as a scientific globetrotter of sorts at various institutes in several countries, concentrating almost always on momentum and energy analyses of the atomic fragments created by collisions between elementary particles. To measure the momentum and energy of several fragments simultaneously, Joachim Ullrich developed recoil-ion momentum spectroscopy. The areas of application of measuring systems of this kind range from processes of disintegration in atoms to measurements of the distribution of momentum in solid and surface investigations.
