Title:
SURFACE STRUCTURES FOR HALO REDUCTION IN ELECTRON BOMBARDED DEVICES
Document Type and Number:
WIPO Patent Application WO2005057603
Kind Code:
A3
Abstract:
An electron sensing device includes a cathode (6, 50) for providing a source of electrons, and an anode (8, 80, 83, 86, 89) disposed opposite to the cathode for receiving electrons emitted from the cathode. The anode includes a textured surface for reducing halo in the output signal of the electron sensing device. The textured surface may include either pits (85) or inverted pyramids (87).
