With ions we have all beam parameters under control, but one: The time structure of an ion pulse. We can adjust ion energies, choose ion species and charge states, tune beam-target geometries, etc., but we cannot determine the impact time of an ion on a solid surface to a precision better than 100ps. This lack of timing precision hinders a direct observation of an ion impact in experiment. In fact, all experimental methods today observe ion-induced effects on/in surfaces on a much later time-scale. Transient ion-induced atomic and electronic effects stay hidden.
Our mission is the development of experimental schemes which allow the direct observation of an ion impact on a solid surface and the ion interaction with short-lived plasmas. The timing-precision we want to reach is 1ps, which is ~100 times better than what can be achieved today.
With the help of the FWF START prize a new group at TU Wien will work over a period of 6 years on directly time-resolved ion scattering. After more than 30 years of development in timing resolution for lasers and electrons, it’s finally time4ions.
