✦ Synopsis

Dual-detector differential non-destructive Fourier transform detection in a quadrupole ion trap is shown to improve signal intensity and reduce noise compared with spectra recorded using a single detector. A larger area detector in each end-cap electrode is machined to fit its hyperbolic shape and so minimize field imperfections on the z-axis. Argon, acetophenone and bromobenzene spectra were recorded to allow a comparison between single- and dual-detector (differential) modes of detection and to demonstrate the improvement achieved with differential detection.

## Abstract A Fourier transform operating mode is applied to an ion trap. The trap is truncated at 2__r__~0~ and presents unwanted defects that induce confinement electric‐field non‐linearities. Ion axial secular‐motion spectrum is examined by experiments near the resonance line β~__z__~ = 0.5. Io
