Zusammenfassung:An embodiment of the invention is an electron multiplier including a first plate having an electron emissive first interior surface. A second plate has an electron emissive second interior surface. A voltage source is connected across the first plate and the second plate. A collector generates a signal responsive to electron multiplication by the first plate and the second plate. The first interior surface and the second interior surface are parallel and are non-planar.
