Abstract: An electron exit window foil for an electron beam emitter having an electron beam generator and operating in a corrosive environment. The electron exit window foil has a sandwich structure with an outer side arranged to face the corrosive environment and an inner side arranged to face the electron beam generator. The sandwich structure comprises, as seen from the outer side to the inner side, a protective layer, for protecting the sandwich structure from the corrosive environment, a supporting layer made of Ti, for providing structural support for the sandwich structure, and a thermally conductive layer made of Al, for conveying heat from the sandwich structure.

Abstract: In some embodiments, a sensor assembly for continuous measurement of at least one dose control parameter of an electron beam during a substantial part of the duration of a sterilizing process of package material includes an electron beam emitter adapted to emit electron beam (e?) from an electron exit window and a sensor device that includes: a sensor surface having an electron excitable material arranged to be radiated with at least a part of said electron beam (e?), so as to excite said electron excitable material so that said electron excitable material emits luminescence and a detector arranged and adapted to detect said luminescence. The electron beam emitter is adapted to emit a continuous electron beam (e?) during a predetermined time period so as to irradiate and sterilize package material.
