Abstract
An ion detection system comprising an upper plate configured for propagation of ions therethrough, a lower plate comprising a converter configured for converting ions impinging thereon to secondary electrons, a secondary electron multiplication assembly configured for receiving the secondary electrons and comprising at least one or optionally a series of oppositely facing pairs of dynodes, wherein in the optional series of oppositely facing pairs of dynodes, each pair is spaced apart from an adjacent pair, and wherein a first electric field is created in between the oppositely facing pair of dynodes. A magnetic system is provided for generating a magnetic field.
