Abstract:
A method for detecting electron beam filament wear in an electron beam source, the method comprising the steps of: enlarging a beam spot emanating from the electron beam source on a work table to a predetermined minimum size, capturing an image of the beam spot on the work table by a camera, comparing the captured image of the beam spot with a reference image, and detecting filament wear if the captured image is deviating more than a predetermined value from the reference image.

Claim (Index 2):
The method according to  claim 1 , further comprising the steps of:\n determining a total area of electron emission less than a predetermined emission value in the captured image within the boundary of the reference image of the reproduced electron emission of the filament onto the target surface, and detecting filament wear if a luminous flux in the captured image is deviating more than a predetermined value from the reference image and/or if the total area of emission less than the predetermined emission value in the captured image is above a predetermined value.
