Abstract (en)
[origin: DE4219562C1] Owing to their necessary thickness, prior art electron beam exit wimdows (Lenard windows) have a high absorption or require cooling systems and expensive supporting structures. The aim is to provide a window which is easy to make with low absorption which avoids these problems. The beam exit aperture is given a vacuum-tight seal in the prior art manner using a metal foil while on the vacuum side a supporting grid of highly heatproof fibre strands secured in a frame is fitted to bear against it. The electron beam exit window is particularly suitable for relative low electron energies with high power density.
