dynamics in nanoscale targets at ELI BeamlinesTuesday, 16 January 2024, 
10:00, KFKI Campus, Bldg. 1, 2nd floor, Conference RoomELI Beamlines facility 
is an international research center operating high-power lasers and 
femtosecond secondary sources of accelerated particles and x-rays for user 
experiments. The MAC end-station at the ELI Beamlines is intended to 
investigations of ultrafast dynamics in low-density targets, such as atomic 
and molecular beams, clusters and nanoparticles, and imaging of solid 
targets. I will focus on various nanoscale samples at the MAC end-station, 
ranging from few-nanometer helium nanodroplets and larger support-free 
dielectric nanoparticles to nanoscale structures on a substrate. In helium 
nanodroplets, I will present studies of secondary processes after irradiation 
with extreme ultraviolet light, relevant to the radiation damage in 
biological matter. These studies include interatomic Coulombic decay, 
collective autoionization in nanodroplets, and production and dynamics of 
transient nanoplasmas. Moving to larger dielectric nanoparticles, I will 
address the mutual interaction of the laser-irradiated nanoparticle with the 
gaseous environment. The presence of an uncondensed gas is very often 
neglected in investigations of nanoparticles in vacuum. However, I will show 
that it can have a dramatic effect on the measured spectra and the 
interpretation of results. Lastly, I will discuss possibilities of lensless 
imaging of solid samples using our high harmonic beamline. Minden
