  We present a combined experimental and theoretical study of the charging
dynamics of helium nanodroplets doped with atoms of different species and
irradiated by intense near-infrared (NIR) laser pulses (<10^15 Wcm-2). In
particular, we elucidate the interplay of dopant ionization inducing the
ignition of a helium nanoplasma, and the charging of the dopant atoms driven by
the ionized helium host. Most efficient nanoplasma ignition and charging is
found when doping helium droplets with xenon atoms, in which case high charge
states both of helium (He2+) and of xenon (Xe^21+) are detected. In contrast,
only low charge states of helium and dopants are measured when doping with
potassium and calcium atoms. Classical molecular dynamics simulations which
include focal averaging generally reproduce the experimental results and
provide detailed insights into the correlated charging dynamics of guest and
host clusters.
