Scientists Meet Scientists

Wednesday Coffee Talk

Prof. Ernst Rank and the TUM-IAS team invite the scientists of TUM and their guests for coffee each Wednesday! Just come over to the TUM-IAS after lunch between 1:00 – 2:00 p.m. and have a coffee with us, meet other scientists and listen from time to time to a short talk (10-15 mins) on a recent major TUM publication or issue – aimed specifically at a non-expert audience.

On June 5, Dr. Christoph Hugenschmidt (Research Group Positron Physics) will report on “A Tricky Experiment: Simultaneous Storage of Positrons and Electrons”. For the first time, scientists from the Technical University of Munich (TUM) and the Max Planck Institute for Plasma Physics (IPP) have succeeded in losslessly guiding positrons, the antiparticles of electrons, into a magnetic field trap. This is an important step towards creating a matter-antimatter plasma of electrons and positrons, like the plasmas believed to occur near neutron stars and black holes (News article).
