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 Prof. Richard A. Wilhelm and funded through the START prize of FWF.

Christmas punsch 2019

A successful year with lot's of work is about to end. The Atomic and Plasma Physics group and time4ions celebrate the Christmas time with some Austrian Punsch. We say thank you for all your support and wish all our friends a Merry Christmas and a happy new year 2020.

Empty space for the time4ions lab Space for the new time4ions EBIS Refurbished beamline 1 at SOPHIE

Lot's of work already done at the Augustin lab. We made space for the new time4ions lab and the new EBIS for our highly charged ion spectrometer NIELS. Also Beamline 1 at SOPHIE is refurbished and almost complete to go online. Exciting new upgrades to our facilities are in place and will allow us to understand the time dynamics of an ion impact in more detail.

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.
