Use of a magnetic quadrupole triplet as a high resolution ion energy spectrometer

Abstract

The use of a nuclear microprobe, containing a magnetic quadrupole triplet, as a high resolution energy spectrometer is proposed here. It is calculated that energy differences of ≈300 eV can be resolved for 3 MeV protons which are transmitted through thin samples, corresponding to an energy resolution of δE≈0.01%. The optics and performance of this energy spectrometer are discussed and compared with other types which are used for ion beam analysis.
