      abstract     = {We use intense femtosecond extreme ultraviolet (XUV) pulses
                      with a photon energy of 92 eV from the FLASH free electron
                      laser to irradiate substrate-free CsCl nanoparticles
                      surrounded by a He gas with a number density of around
                      10$^{15}$  cm$^{−3}$. By simultaneously detecting
                      electrons and energetic ions from the laser-irradiated
                      micron-size target we study the acceleration mechanism of
                      light ions at the microplasma-vacuum boundary as well as at
                      the layer close to the nanoparticle surface. When the XUV
                      pulse interacts with the gas alone, helium ions are
                      accelerated to energies exceeding 100 eV. In the presence of
                      the nanoparticle, light ions gain additional energy in the
                      electric field around the ionized nanoparticle and their
                      energy spectrum changes considerably. We present an
                      electrostatic model to explain the ion acceleration
                      mechanisms both with and without the nanoparticle and
                      discuss the role of the gas environment in experiments.},
