Dirk Dubbers

Dirk Dubbers , actually: Dietrich Jochen Dubbers, (born November 16, 1943 in Dresden ) is a German experimental physicist who is particularly concerned with neutron physics.

Life

Dubbers attended the high school in Tübingen , as well as high school in Ann Arbor , Michigan for a year . He studied physics at the Georg-August-Universität Göttingen and the Ruprecht-Karls-Universität Heidelberg , where he received his doctorate in 1972 ( investigation of the reorientation of nuclei in solids using beta and gamma decay anisotropies after the capture of polarized neutrons ). As a post-doctoral student , he worked at the European neutron source of the Institut Laue-Langevin (ILL) in Grenoble from 1972 to 1975 . His research area at that time was nuclear solid-state physics . In 1978 he completed his habilitation in Heidelberg. From 1985 to 1990 he was a senior scientist at the ILL, researching the role of the neutron in particle physics and cosmology. In 1991 he became a professor at the Technical University of Munich and from 1993 until his retirement in 2011 he was a full professor for experimental physics at the Physics Institute of the Ruprecht-Karls-Universität Heidelberg. Dirk Dubbers was the director of the ILL from 1998 to 2001 as the successor to Reinhard Scherm , and from 2001 to 2003 dean of the Heidelberg Faculty of Physics and Astronomy.

According to a press release from February 2015, he and other physicists at Heidelberg University came to the conclusion that the Federal Republic of Germany was aiming for a change to renewable energies, that what has been achieved so far is far from being sufficient and that even if all households switch to electrical power from renewable energies, their share in the Total energy consumption (i.e. not just electricity, but also the transport and heating sectors) would only be 4 percent. Overall, the share of renewable energies (with a clear focus on biomass in the form of wood, sewage gas, biodiesel) in 2016, according to the study, was only 13 percent of energy consumption despite great efforts to expand wind energy.

Awards

• In 1991 he and Walter Mampe received the Stern-Gerlach Prize of the German Physical Society for precision measurements of the weak coupling constant during beta decay.
• In 2012 he received an honorary doctorate from the Technical University of Vienna .
