Joachim Stöhr

Joachim Stöhr (born September 28, 1947 in Meinerzhagen ) is a German experimental physicist who studies surfaces with X-rays .

Life

Stöhr studied at the University of Bonn and received his doctorate from the Technical University of Munich in 1974 . As a post-doctoral he was at Lawrence Berkeley National Laboratory and in 1977 scientists at the synchrotron radiation source Stanford Synchrotron Radiation Laboratory (SSRL), where he, among other techniques for examining surfaces with soft X-rays (as SEXAFS , NEXAFS developed). From 1985 he was at the IBM Almaden Research Center. From 2000 he was a professor at Stanford University and deputy head of the SSRL, where he became director in 2005. In 2009 he became director of Linac Coherent Light Source at SLAC . There he researched in particular thin magnetic films and nanostructures using X-ray techniques, which resolve temporally in the femtosecond range and spatially in the nanometer range.

In 2011 he received the Davisson-Germer Prize for the development of spectroscopic and microscopic techniques based on soft X-rays with fundamental applications in the research of chemical bonds, magnetism and the dynamics of surfaces . He has been a Fellow of the American Physical Society since 1988 .
