| Popis: | In order to measure different isotopes with fixed multi-collectors at a Mass Spectrometer conveniently, a zoom lens with two electrostatic quadrupoles is chosen to adapt the dispersions from different isotopes. A design method of such a zoom lens is introduced in this paper. Based on theoretical modelling results, validation of zoom effect and focusing performance has been carried out through SIMION simulation of two different electrostatic quadrupole devices: pole-type and segment-type. Then, electric voltage corrections have been applied considering the inconsistencies. Finally, the design requirements are satisfied. |
