Abstract
A charged particle collector assembly, particularly for use with an electron beam gun, is described. The assembly comprises a reflection member onto which electrons impinge in use, the reflection member being adapted substantially to absorb particles of one polarity and substantially to reflect particles of the other polarity. A sensor or collector is positioned to receive particles reflected from the reflection member and to generate a corresponding output signal.
