11.02.2014 Applied Physics B Special Issue is Online

The topical issue "Frontiers of ion trap and atomic physics: Wolfgang Paul 100" is online. In order to commemorate the 100th aniversary date, the editors Ferdinand Schmidt-Kaler, Rainer Blatt and Günter Werth take the opportunity to edit a special volume in ion trap physics. Even though the invention of the Paul trap dates back to more than half a century, the contributions to this volume clearly hallmark the active ongoing research with Paul traps (more...).

 

10.02.2014 Cooling Antihydrogen Ions for thr Free Fall Experiment GBAR

Does Matter fall on earth exactly like antimatter would do? This fundamental question is still not answered experimentally. Researchers from the Johannes Gutenberg University Mainz and the GBAR Collaboration (http://gbar.in2p3.fr/, http://gbar.web.cern.ch/GBAR/ ) discuss the necessary experimental steps to catch, trap and sympathetically cool Anti-H ions (p-, 2x e+) in a mixed crystal containing 9Be+ ions (http://arxiv.org/abs/1402.1695). The setup of an experiment is funded in parts by the Cluster of excellence PRISMA and with our French partners within a common ANR-DFG project.
