A device and a method for creating a spatial dose distribution in a medium volume () are described. A laser system produces laser pulses () with a pulse length shorter than 200 fs (femtoseconds) and is capable to be focused to peak intensities greater than 10^18 W/cm^2 (watts per centimeter squared). An electron source () is capable of releasing a high-energy electron pulse (), in particular the electrons having an energy greater than 100 MeV, upon irradiation with said laser pulses () propagating into the medium volume (). The light paths () of at least some of the laser pulses () are adjustable in such a way that high-energy electron pulses () are emitted from the irradiated at least one electron source on different trajectories () through the medium volume () thereby depositing their dose in the medium volume () according to a provided pattern.
