- •
A theoretical model for the design of Electrostatic Quadrupole Zoom Lens has been established, and validated by SIMION.
- •
Segment-type quadrupole zoom lens with a better flexibility has been proposed and investigated.
- •
Study shows electrostatic quadrupole doublet is CD-type for m > 1.0, and DC-type for m < 1.0.
- •
Study shows the theoretical model performs well if the first order approximation is satisfied.
- •
Voltage corrections can compensate dissatisfaction of paraxial approximations somehow, giving a satisfactory performance.
