Abstract
An ion detection system includes a mass analyzer generating an ion beam along an ion beam longitudinal axis. A field generator generates a field for altering the direction of ions in the ion beam away from the ion beam longitudinal axis. A conversion dynode includes an ion collision region on a conversion dynode surface. A conversion dynode axis passes through the ion collision region perpendicular to the conversion dynode surface, the conversion dynode axis being offset from and not intersecting the ion beam longitudinal axis. An electron multiplier receives secondary charged particles from the conversion dynode generated in response to the ion collision with the conversion dynode surface.
