An EBIT for Fundamental Ion-Laser Interaction and Strong Field Ionization Studies

  • Client: Friedrich-Schiller-Universität Jena
  • Date of launch: Jun, 2009
  • Place: Jena, Germany


The Nonlinear Optics group of the Institute of Optics and Quantum Electronics at Friedrich Schiller University, Jena, Germany, uses an EBIT combined with a Wien filter as well as an einzel lens designed and manufactured by DREEBIT GmbH to study ion-laser interactions and strong-field ionization. A Wien filter separated beam of ions or ionic molecules crosses an intense few-cycle laser beam leading to multiple ionization in the laser field. The final ion charge state and the momenta of the resulting free electrons are recorded using time and position sensitive detection methods. Based on these investigations models of the ionization dynamics in few-cycle laser fields can be developed which helps to understand fundamental processes during the creation of laser plasmas.
