Overview of project C05
Exploring Particle-Induced Excitations in the Time Domain
Schleberger, Sokolowski-Tinten, Wucher
The impact of an energetic particle onto a solid surface generates a strongly perturbed and extremely localized non-equilibrium state, which relaxes on very fast time scales. In order to facilitate a time-resolved observation of the relaxation dynamics using established ultrafast pump-probe techniques, it is necessary to pinpoint the projectile impact in time with sufficient accuracy. In this project, we are currently developing a novel ion source which is designed to generate ion pulses of (sub-) picosecond duration. This way, it will be for the first time possible to access the ultrafast ion impact-induced dynamics with an experimental technique.
Detailed ion trajectory simulations (for details see New J. Phys. 21 (2019) 053017 ) show that single ion pulses of sub-picosecond duration can be generated via femtosecond photoionization of rare gas atoms entrained in a supersonic jet. The photoion cloud will be produced with a standard table-top laser system. We could show that Arq+ ions with q = 1–5 can be generated, which are then accelerated to energies in the keV range over a very short distance and bunched to impinge onto the target surface in a time-focused manner. Charge state broadening is insignificant for pulses containing up to 10–20 ions and starts to increase the pulse width only above ~50 ions/pulse.
The realization of a corresponding experimental set-up is now nearly finished and currently being tested in our lab. Once laser-generated ultrashort ion pulses are available, they will be utilized for time resolved studies of, for instance, the local lattice disorder, the transient electronic excitation and the ion-induced particle emission (“sputtering”) following a keV projectile impact.
