Ties Behnke
Experimental Particle Physics
Ties Behnke is lead scientist at DESY, working in the field of experimental particle physics. For many years, he has been working in the field of weak interaction physics, including the measurement of Standard Model parameters with heavy quarks and the development of experimental methods and detectors. He participated in the D0 experiment at the Tevatron proton-antiproton collider, the OPAL experiment at the LEP electron-positron collider, and led the measurement of electron polarisation at HERA. He was a member of the TESLA team at DESY, and later worked on the International Linear Collider, ILC. Here he coordinated an international team of scientists who proposed a detector concept for an experiment at high energy electron positron colliders, the ILD experiment.
Since 2012 he is the speaker of the Helmholtz Programme "Matter and Technologies" which deals with enabling technologies for the research field matter, in the area of accelerators, detectors and computing. In 2021 he was interim director of particle physics at DESY. In his own research Ties Behnke is interested in electroweak physics, and in tracking detectors, for example, time projection chambers or semi-conductor detectors.
