Low voltage electron beam dosimeter device and method

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.
