Logo time4ions

The newly established research group will combine ultrafast laser techniques with ion beam technology to investigate ultrafast processes in solid surfaces, which are induced by an ion impact. One major part of the efforts is the development of a pulsed, laser-driven ion source which delivers pulses as short as 1ps. The group is lead by Dr. Richard A. Wilhelm and funded through the START prize of FWF.

We are seeking talents

There are several PhD positions available for excellent students. We also offer Master, Bachelor, and Project Thesis options in the group. Please contact [email address: lastname @ this server · enable javascript to see it] for detailed information.



Johanna_Waldemar Two new group members! Welcome Johanna and Waldemar!! Both are new Master students in the time4ions group, Johanna will do Simion simulations and optimizes the future ion source design. Waldemar is redesigning Beamline 1 of our larger ion beam setup to perform light ion transmission through freestanding 2D materials.


HZDR Successful beamtime at Helmholtz-Zentrum Dresden-Rossendorf. Anna and Richard went to the HZDR to perform Medium Energy Ion Transmission (MEIT) of light ions through 2D materials taking full advantage of the high energy resolution of a toroidal energy analyzer.


ICPEAC Roadmap for research on heavy particle collisions published. This Roadmap points towards future developments in the field and specifically names time-resolved ion scattering as one major development to be expected in the near future. We are part of it!


Anna Anna_b

Poster Prize for Anna at the ICPEAC2019 conference! This conference has about 600 participants and Anna was awarded for her poster on 'The role of contaminations on the interaction of highly charged ions with 2D materials'. Congratulations, Anna!


The project is supported by FWF START (Y 1174-N36) and by TU Wien (Innovative Projects).
