The ionization dynamics of atomic clusters in intense ultrashort laser pulses has been an active area of research in recent years at near-infrared (NIR), vacuum-ultraviolet, and soft x-ray wavelengths [1-3]. Doped He nanodroplets are particularly interesting heterogeneous systems due to extremely different masses and ionization energies of guest and host atoms as well as due to the peculiar quantum properties of He nanodroplets. We present a new mobile and versatile apparatus for producing beams of doped He nanodroplets that will be employed for strong-field ionization studies using few-cycle laser pulses as well as for synchrotron and FEL experiments.
