A VMI spectrometer for nanoplasma experiments — •Nicolas Rendler1, Dominik Schomas1, Robert Moshammer2, Thomas Pfeifer2, and Marcel Mudrich1 — 1Albert-Ludwigs-Universität Freiburg — 2Max-Planck-Institut für Kernphysik
We present a new apparatus to explore the dynamics of helium nanoplasmas via NIR and XUV femtosecond pump-probe experiments. Doped helium nanodroplets feature complex plasma ignition dynamics strongly depending on the dopant properties. The newly designed velocity map imaging (VMI) spectrometer is capable of mapping high energy electrons and ions (<250 eV) occurring in Coulomb exploding nanoplasmas. Fragment ions formed in the nanoplasma expansion will be analyzed simultaneously using a high-voltage time-of-flight (TOF) mass spectrometer mounted in the same setup.
