CHARGED PARTICLE SPECTRUM ANALYSIS APPARATUS

摘要

A charged particle spectrum analysis apparatus comprising an electric field generator arranged to subject charged particles to a time-varying electric field, a detector to record charged particle time spectrum data of charged particles which have passed through the electric field, the detector comprising a position-sensitive detection portion, and the time-varying electric field arranged to be activated in synchrony with activation of detector, and the time-varying electric field arranged to subject a predetermined region of said detection portion to consecutive charged particle deflection cycles.
