ABSTRACT:
An arrangement for curing, by electron beam irradiation, a lacquer coating carried on an article having a complex configuration. The arrangement includes an assembly formed of an electron accelerator for obtaining highly accelerated, high-energy electrons and a scanner for forming, from the electrons, a spread-out electron beam directed onto the article through an electron outlet window. The article has a first surface position inaccessible to direct electron beam radiation and a second surface portion arranged at an oblique angle with respect to the direction of the direct electron beam radiation and exposed to the direct electron beam radiation. The second surface portion is further oriented towards the first surface portion, whereby one part of the electrons impinging on the second surface portion is reflected therefrom onto the first surface portion.
