Abstract :
Intense pulsed electron beams are used to improve properties of metals in near-surface regions or for surface alloying. One of the pulsed electron beam facilities (GESAIV) at KIT has a cylindrical converging electron beam for outer tube treatment. The power density of the generated beam is 0.5-2 MW/cm2, the electron energy 120 keV, pulse duration up to 200 μs and the treatable length with a single beam 30 cm. One design specific of this type of e-accelerator is the axial current flow along the anode, which is commonly also the target [1].
