The known electron beam outlet windows (Lenard tube) have a high absorption as a result of the required thickness of the foil or use cooling devices and complex support structures. By avoiding these disadvantages, a simple-to-produce window with low absorption can be produced. The beam outlet window in known devices is enclosed in a vacuum-tight metallic foil and, resting on it on the vacuum side is a support grid made of high-temperature-resistant fibre bundles attached in a frame. The electron beam outlet window is specially suited for relatively low electron energies at high electron beam power density.
