The invention relates to a device and a method for altering the characteristics of a three-dimensional shaped part (2) using electrons. Said device comprises at least one electron accelerator (3a, 3b) for generating accelerated electrons and two electron discharge apertures (5a, 5b), the apertures (5a, 5b) lying opposite one another and together with at least one reflector (7a1, 7a2, 7b1, 7b2) delimiting a process chamber, in which the surface or an edge layer of the shaped part (2) is bombarded with electrons. According to the invention, a sensor system is used to detect an energy density distribution inside the process chamber, at least in one spatial dimension. |
