Setup and first experiments with a new attosecond strong-field reaction microscope — •Martin Laux, Christian Ott, Philipp Raith, Andreas Kaldun, Claus-Dieter Schröter, Robert Moshammer, Joachim Ullrich, and Thomas Pfeifer — Max-Planck-Institut für Kernphysik, Heidelberg, Germany

We present the experimental setup of a new reaction microscope to study interactions of ultrashort light pulses with atoms or molecules which is currently being constructed in our attosecond laboratory. The instrument allows to measure, in coincidence, the momenta of ions and electrons produced within the interaction. The reaction microscope is designed to detect electrons up to a kinetic energy of at least 100 eV to be matched to similar photon energies exhibited by our soft-x-ray attosecond pulses. The target can be any atomic or molecular gaseous system of interest but the first experiments will concentrate on strong-field interactions with rare gases to judge the performance of the instrument. The setup of the reaction microscope, including important design considerations, and the first experimental results along with some simulations will be shown. Finally, we will provide an outlook on future experiments now possible with the new device.
