A new helium droplet source setup for nanoparticle deposition — •Fabio Zappa, Anna-Maria Reider, Thomas Pohl, Jan Mayerhofer, Masoomeh Mahmoodi-Darian, Elisabeth Gruber, and Paul Scheier — Institut für Ionenphyik und Angewandte Physik - Universität Innsbruck

Helium droplets have been extensively used in the last years to produce taylor-made clusters of various atomic and molecular species, which can be analysed both in *in flight* or deposited on surfaces. Surface deposition with helium droplets presents various challenges as well as opportunities which our group is presently exploring. The present communication gives an overview of a new setup that is being developed in our group, which will allow the deposition of doped helium droplets both in neutral or multiply charged state. Various benchmarks and comparisons with other instruments in our lab will be presented, as well as preliminary deposition results with gold as dopant of the droplets.

The work was supported by the Standort Agentur Tirol, K-Regio Project SupremeByNano
